What Causes the “Change Drive Letter and Paths Greyed Out” Issue

Why you can’t change drive letter and paths Windows 10? According to a survey, the main reason behind the issue is that you are using a Mac formatted drive on Windows. It’s known that the mac hard drive is formatted to an HFS+ file system that can’t be accessed on a Windows PC. Usually, this situation often appears on an external storage device.

On an internal hard drive, the following situations may cause you can’t change drive letter and paths Windows 10.

  • You are changing a system partition or a boot partition’s drive letter. Usually, the system partition was assigned with C by default.
  • The drive letter you are trying to change might be in use. In this case, you can close all running programs and try again.
  • The drive letter has already been used by some external storage device.

How to Do If You Can’t Change Drive Letter

If you are still troubled by the “change drive letter and paths greyed out Windows 10” issue, you can try the following methods.

Method 1. Connect the Drive to a Supported Operating System

As mentioned above, the main reason for the change drive letter and paths greyed out error is due to an unsupported operating system. So, the easiest and direct way is to use the drive on a Mac or other supported computer. If not, you won’t be able to access its data on Windows unless you use a professional data recovery tool or format it to a supported file system.

Method 2. Format Mac Hard Drive on PC

If you don’t have a Mac computer, then you may consider formatting the drive to NTFS/FAT32 and assign a letter. How to format a Mac hard drive on Windows? Microsoft provides some built-in tools that can be used to format a hard drive, including Diskpart, Disk Management, and File Explorer.

Here we take Diskpart for example:

Using Diskpart:

Step 1. If you are using an external drive, make sure you connected it to the computer.

Step 2.  Press  Win + R  keys to open the  Run  dialog box, and then type  diskpart  in the box and hit  Enter .

open diskpart command prompt via the Run box

Step 2.  In the Diskpart window, type the following commands one by one and hit  Enter  after each typing. Once you finished the command below, your drive should be formatted to NTFS or FAT32

  • select disk * (replace * with the number of your connected drive)
  • list partition
  • select partition 1 (the 1 represents the partition you want to format)
  • format fs=ntfs quick or format fs=fat32 quick

formating an external drive with Diskpart

Step 3. Proceed with the following commands if you want to assign a drive letter for the drive.

  • Select disk 1 (the 1 represents the disk you want to create a partition in)
  • create partition primary size=x  (x represents the extended partition size in MB)
  • assign letter=E (replace E with the letter you want to assign for the drive)

assign a drive letter using Diskpart

Diskpart helps you format hard drive and create partitions. Sometimes, however, you may encounter the “ no usable free extent could be found ” and “ Virtual Disk Service Error ” and while using Diskpart. In addition, this tool can’t help you format a drive larger than 64GB to FAT32. To format a drive quickly and safely, we recommend you use MiniTool Partition Wizard.

I love that the changes you make with EaseUS Partition Master Free aren't immediately applied to the disks. It makes it way easier to play out what will happen after you've made all the changes. I also think the overall look and feel of EaseUS Partition Master Free makes whatever you're doing with your computer's partitions easy.

Partition Master Free can Resize, Move, Merge, Migrate, and Copy disks or partitions; convert to local, change label, defragment, check and explore partition; and much more. A premium upgrade adds free tech support and the ability to resize dynamic volumes.

It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.

Change a drive letter

  • 4 contributors
Applies To: Windows 11, Windows 10, Windows Server 2022, Windows Server 2019, and Windows Server 2016

If you want to change a drive letter assigned to a drive, or you have a drive that doesn't yet have a drive letter, use Disk Management to change it. You can also mount the drive in an empty folder so that it appears as a folder. For more information, see Mount a drive in a folder .

If you change the drive letter of a drive that already contains Windows or apps, apps might have trouble running or finding the drive. We suggest not changing the drive letter of a drive that already contains Windows or apps.

The following steps show how to change the drive letter.

Open Disk Management with administrator permissions.

In Disk Management, select and hold (or right-click) the volume on which you want to change or add a drive letter and select Change Drive Letter and Paths .

Screenshot showing the Disk Management window with the Change Drive Letter and Paths feature selected.

If you don't see the Change Drive Letter and Paths option or it's grayed out, the volume either isn't ready to receive a drive letter or it's unallocated and needs to be initialized . It might also be that the drive isn't accessible, which is the case with EFI system partitions and recovery partitions. If you've confirmed that your volume is formatted with a drive letter that you can access but you're still unable to change it, that's beyond the scope of this article. We suggest contacting Microsoft Support or the manufacturer of your PC for more help.

To change the drive letter, select Change . To add a drive letter if the drive doesn't already have one, select Add .

Select the new drive letter and choose OK . Then select Yes when prompted about how programs that rely on the drive letter might not run correctly.

How to change a drive letter on windows 10 or windows 11.

You can change your drive letters in Windows 10 and 11 using the Disk Management utility.

Quick Links

What changing a drive letter does, how to change a drive letter, how to fix programs broken by changing a drive letter.

Changing the letter of a drive is easy on Windows 10 and Windows 11, but you should do it as soon as you add the drive to prevent future hassles. Find out how to change a drive letter here.

Windows assigns drive letters alphabetically --- starting with C --- when they're initialized. If you want to change a drive letter, you should do it before you install anything on the drive. Changing a drive letter after programs are installed could break them since there will be references to an installation location that is no longer there.

Windows has gotten pretty smart about updating shortcuts so that programs work after changing a drive letter. Most of your applications' shortcuts will probably be automatically corrected. Unfortunately, Windows isn't as good about updating file associations. You'll have to manually set the default apps associated with files to fix file associations if they were broken by changing the drive letter.

It is possible to change the boot drive letter to something else, but we don't recommend it. Changing C:\ to another letter is likely to result in severe issues, like a PC that cannot boot into Windows at all. Even if it were able to boot, there would be a huge number of programs that would not be able to run.

Technically speaking, while they are commonly called drive letters, each letter actually refers to a partition on a disk. If you have multiple partitions on a single disk, you will need to assign a letter to each partition to make them all accessible. If a disk has just a single partition, it will just have a single letter pointing to that partition. (However, you do not have to assign a letter to each partition. Partitions without drive letters will not appear in File Explorer and elsewhere.)

Changing a drive letter is pretty simple. Click the Start button, type "Disk Management" in the search bar, and then hit Enter.

The program name displayed in the search will not be Disk Management. It will be "Create and format hard disk partitions."

Start menu search showing disk manager result is not called disk manager

You could also hit Windows+X or right-click the Start button, and then click "Disk Management."

Click

Identify the drive you'd like to change in the Disk Management Window. In this example, we'll change the letter of the D:\ drive to J:\. You can right-click the drive on the text list, or on the menu below. Either works.

Right click the drive in the list, or right click the drive on the menu at the bottom.

Select "Change Drive Letter and Paths" in the right-click menu that appears.

Click

In the window that pops up, click "Change."

Click

Select whatever letter you want from the drop-down menu. Then click "Ok."

Select letter from drop down menu, then click

Two popups will warn you about changing your drive letter. Click "Yes" on both of them, and then restart your computer.

Once Windows has restarted, the drive letter should be changed.

Arrow pointing to change drive letter.

There are a few ways you can fix a program broken by changing the drive letter.

Fix The Shortcut

If you're lucky, the only thing that is broken is the shortcut. Fix a shortcut by right-clicking the shortcut on your desktop, and then click Properties.

Click

You need to change the target of the shortcut to the new drive letter.

For example, if GIMP was previously installed at " D :\GIMP 2\bin\gimp-2.10.exe," and you changed the D drive to J, change the target of the shortcut to " J :\GIMP 2\bin\gimp-2.10.exe."

Finalize the change by clicking "Apply" and then "Ok."

Edit the shortcut. Then click

Reinstall the Program

Reinstalling the program will generate new entries in the registry, so everything on the computer will know where to look for the program. Some installers won't like reinstalling directly over existing files, so you may need to rename or delete the old installation first.

Change the Drive Letter Back

If you changed the drive letter of a drive with a lot of programs installed, it might be easier to change the drive letter back. Changing the drive letter back should automatically fix any programs and file associations that were broken.

Edit the Registry

You can break programs, or even Windows itself, by editing the registry. Be careful, and learn about how to edit the registry before you try it. Make sure you backup the Windows registry first. You should not attempt this method unless you have no other options.

Windows, and a lot of programs, track where programs are installed via the Windows registry. It is possible to manually adjust the registry to fix broken programs. Keep in mind that there could be dozens of registry entries you need to edit. A program like GIMP can have registry entries for the context menu, for the "Open With" menu, for any file associations, and for the location of its executables. Other programs may only have a few entries related to where it is installed.

If you're not deterred, here's how you do it.

First, you need to know where the program was previously installed. In this case, the program was installed to the "D:\GIMP 2" folder, and the executables were found the "D:\GIMP 2\bin" sub-folder. It is now located at "J:\GIMP 2" instead.

We need to update the registry to reflect the change in location. Click the Start button, type "regedit" into the search bar, right-click Regedit, and click "Run as administrator."

Click

In Regedit, hit Ctrl+F to bring up a search window. Type in the old location for the program you're trying to fix --- "D:\GIMP 2" for our example --- then click "Find Next."

Click

Once Regedit has found something with "D:\GIMP 2" as part of a path, it'll show it to you. Here is an example from the GIMP search.

Some of the GIMP search results found in the registry.

To actually change them, double click the name of the registry entry you want to modify. Then change the drive letter to J, or whatever you chose. If you didn't otherwise move the folder, leave the rest of the path alone. Then click "Ok."

Change the drive letter in Value Data.

You'll need to repeat this multiple times. To find the next result using your search term, you can hit the F3 key. There will be a popup once you've found all of the entries.

Changing drive letters can be a simple way to customize your PC. Do it before you install anything on the drive, however. You'll prevent any problems before they occur, and probably save yourself quite a bit of troubleshooting.

Reasons Why Change Drive Letter and Paths May Be Greyed Out

Knowing why the Change Drive Letter and Paths option is greyed out can help you determine which fix is appropriate, as well as help you pick the best option to secure your data.

Some things that can lead to a greyed out Change Drive Letter and Paths option are:

How to Fix the Change Drive Letter and Paths Option Greyed Out Issue

There are several ways to diagnose a greyed out Change Drive Letter and Paths option. In the worst-case scenario, you will need to format the drive for the option to become accessible. That’s why, it’s best to back up all your important data from the drive, especially if the drive exhibits symptoms of logical damage.

If the drive works flawlessly, you can simply copy the required files to a safe location. But, in case you suspect the disk is logically damaged, or you’re unable to access it in Windows Explorer, you’ll need to create a disk image of the drive. A disk image is essentially a soft copy of the entire drive. You can use it to restore your existing data, and even recover deleted files.

We recommend you use Disk Drill to create the disk image, since it’s compatible with all types of storage drives and works with Windows, Linux, and macOS file systems. You can also mount the disk image in Disk Drill and use it to recover existing, as well as deleted files .

Here’s how to create a disk image (backup) of your drive using Disk Drill:

  • Download and install Disk Drill.
  • Open Disk Drill, and go to Drive Backup under Extra Tools .

Byte-to-byte Backup screen.

  • Disk Drill will create the disk image.

Once your files are secured, you can proceed to fix the Change Drive Letter and Paths option not available issue.

Method 1: Run Disk Management as an Administrator

All user accounts on your PC do not have the same privileges. To ensure you have the highest level of access, run Disk Management using an Administrator account. Here’s how to do this:

  • Click on the Start button or press the Windows key.

Sign out option in Windows.

  • On the log in screen, select the Administrator user account or any account that has Administrator level access and sign in using that.
  • Search for “disk management” in Windows Search ( Windows Key + S ). Click on Create and format hard disk partitions from the search results.

Change Drive Letter and Paths option.

Method 2: Connect the Drive to a Mac

If your drive worked properly on macOS, it’s best to reconnect it to a Mac and format it to a Windows-recognized file system. You can also take this chance to copy any important files to another location.

Once you’ve connected your drive to a Mac, format it to FAT32, and it should work properly with Windows. Here’s how to format the drive in macOS:

  • Go to Finder > Go > Utilities > Disk Utility . You can also search for “Disk Utility” in macOS’ Spotlight Search ( Command + Spacebar ).

Erase option in macOS.

  • Once the drive has been formatted, reconnect it to your Windows PC. The Change Drive Letter and Paths option should no longer be greyed out.

Method 3: Change the Drive Letter Using the Command Prompt

Whether you’re using an ancient version of Windows, or the relatively newer Windows 7/8/8/1/10/11, you can force Windows to perform drive letter assignment. How? Well, using Diskpart , a command-line tool that can be run using the Command Prompt.

Here’s what the process looks like:

  • Search for “cmd” in Windows Search ( Windows Key + S ). Right-click on Command Prompt > Run as administrator .

Diskpart command.

  • Identify the partition whose drive letter you wish to change. You can do this by looking at the values in the Size and Fs (file system) fields.

Select volume command.

  • Windows will assign the requested drive letter.

Method 4: Format the Drive

If all else fails, you’ll need to format the drive in order to fix a greyed out Change Drive Letter and Paths option. Formatting will clean the disk and rewrite the file system to your drive, giving you a fresh start. It can also fix minor logical issues on the drive.

Here’s how you can format a drive in Windows:

  • Press Windows Key + R to open the Run app. Type diskmgmt.msc in the text box and press Enter.

Format option in Disk Management.

  • Windows will format the drive.

How to Recover Data From a Drive that You Had to Format

If you created a disk image of your drive, your’e good to go and we’ll describe how you can recover data from it. If you didn’t, and had to format your drive, you can still scan the drive directly and recover data, provided the Quick Format option was enabled while formatting. But, you may not be able to recover all your data, especially if you wrote new files to the drive after formatting it.

For our tutorial, we’ll use Disk Drill to perform data recovery as it’s easy to use, has a proven track record, and will work with your drive regardless of its file system and manufacturer. It can also recover data from drives that are RAW, i.e., have no file system at all. On Windows, you can take advantage of Disk Drill’s free trial that lets you recover up to 500 MB of files for free.

Let’s see what the data recovery process looks like in Disk Drill:

  • Download Disk Drill if you didn’t earlier.
  • Open Disk Drill and ensure you’re on the Storage Devices screen. Skip the next step if you didn’t create a disk image earlier.

Attach disk image option in Disk Drill.

  • Disk Drill will recover the selected files.

What To Do If You Encountered “Can’t Change Drive Letter Parameter Is Incorrect”

A common error that you may face when attempting to change the drive letter of a disk or partition, is the “Parameter is incorrect” message .

Use one of these methods to combat this error:

  • Use CHKDSK to resolve possible file system errors and bad sectors on the drive.
  • Convert the partition to NTFS , if it is RAW.
  • Update outdated drivers to ensure the best possible communication between your drive and Windows.

Often, a greyed out Change Drive Letter and Paths option is a result of an incompatible file system or insufficient user account permissions. But, since logical and physical damage can also lead to the issue, it’s best to back up all important files from the drive as soon as you can. Thereafter, you can proceed to resolve the problem using the methods described above.

Importantly, do not attempt DIY data recovery on a drive that’s physically damaged. It’s best to contact a professional data recovery service in such a case.

How to Change a Drive Letter

Don't like the letters assigned to your drives in Windows? Change them!

not able to change drive letter and paths

  • Emporia State University

not able to change drive letter and paths

  • The Ultimate Laptop Buying Guide

What to Know

  • Open Disk Management. Locate the drive you want to change. Right-click and choose Change Drive Letter and Paths > Change .
  • Select the drive letter you want to assign from Assign the following drive letter . Then select OK and choose Yes .

The letters assigned to your hard drives, optical drives, and USB drives in Windows are not fixed. Use the Disk Management tool in Windows to change drive letters. These steps apply to Windows XP and newer versions of Windows .

How to Change Drive Letters in Windows

Follow these steps to change the driver letters in any version of Windows.

You can't change the drive letter of the partition that Windows is installed onto. On most computers, this is usually the C drive.

Open Disk Management , the tool in Windows that lets you manage drive letters, among [many] other things.

In Windows 11/10/8, Disk Management is also available from the Power User Menu ( WIN + X  keyboard shortcut) and is probably the quickest way to open it. You can also start Disk Management from the Command Prompt in any version of Windows, but starting it via Computer Management is probably best for most of you.

Locate from the list at the top, or from the map at the bottom, the drive you want to change the drive letter of.

If you're not sure that the drive you're looking at is really the one you want to change the drive letter for, you can right-click or tap-and-hold the drive and then choose Explore . If you need to, look through the folders to see if that's the right drive.

Right-click or tap-and-hold the drive and choose Change Drive Letter and Paths .

Select Change .

If you've selected the primary drive by accident, some versions of Windows will display a message that reads Windows cannot modify the drive letter of your system volume or boot volume.

Choose the drive letter you want Windows to assign to this storage device by selecting it from the Assign the following drive letter drop-down box.

You don't need to worry if the drive letter is already being used by another drive because Windows hides any letters you can't use.

Select OK .

Choose Yes to the Some programs that rely on drive letters might not run correctly. Do you want to continue? question.

If you have software installed to this drive, it might stop working properly after changing the drive letter. See details on this in the section below.

Once the drive letter change is complete, which usually only takes a second or two, you're welcome to close any open Disk Management or other windows.

The drive letter is different from the volume label. You can change the volume label using similar steps .

If You Have Programs Not on the Main Drive

Changing drive letter assignments for drives that have software installed to them may cause the software to stop working. This isn't quite as common with newer programs and apps but if you have an old program, especially if you're still using Windows XP or Windows Vista, this is likely to be a problem.

Fortunately, most of us don't have software installed to drives other than the primary drive (typically the C drive), but if you do, consider this your warning that you might need to reinstall the software after changing the drive letter.

No Changes for the Operating System Drive

You cannot change the drive letter of the drive that the Windows operating system is installed on. If you'd like Windows to exist on a drive other than C , or whatever it happens to be now, you can make that happen but you'll have to complete a clean install of Windows to do it. Unless you have a pressing need to have Windows exist on a different drive letter, we don't recommend going through all that trouble.

Change, Don't Switch

There's no built-in way to switch drive letters between two drives in Windows. Instead, use a drive letter that you don't plan on using as a temporary "holding" letter during the drive letter change process.

For example, let's say you'd like to swap Drive A for Drive B . Start by changing Drive A's letter to one that you don't plan on using (like X ), then Drive B's letter to Drive A's original one, and finally Drive A's letter to Drive B's original one.

Using the Command Prompt

You can also change the drive letter from Command Prompt . It's not as easy as using Disk Management and you can't see right away which letters are available to choose, but it is completely doable with the diskpart command.

Error: Windows 11 Disk Management cannot assign drive letter

"I want to use Disk Management to assign a drive's letter so that it can be easily recognized in my computer later, but the "Change Drive Letter and Paths" option is grayed out in my Windows 11 PC. Why Windows 11 Disk Management cannot assign drive letter? Can anyone help me? Thank you very much. "

Why Windows 11 Disk Management cannot assign drive letter?

Windows 11 Disk Management  is a built-in tool for Windows 11 that has the ability to help users with common disk problems, including delete volume, format volume, extend/shrink volume, mark partition as active, add mirror, etc. 

windows 11 disk management

However, sometimes this tool also fails to complete some tasks, like "Change Drive Letter and Paths" greyed out . Why users cannot assign drive letter with Disk Management? We found two most common reasons:

◐ File system:  When the file system of the target partition is not FAT or NTFS , the partition cannot be compatible with the Windows system, and the user will fail to change the drive letter. ◐ The target drive is write-protected: When the target drive is write-protected , it's set to "read-only", so the users cannot successfully assign this drive letter.

How to get out of the "swamp" that Disk Management can't assign drive letter? In the following content, we will propose solutions according to the above two reasons.

2 methods: Solve Windows 11 Disk Management cannot assign drive letter

When Disk Management Assign Drive Letter greyed out, we can take the following two measures to solve the problem in a targeted manner.

│ Method 1. Format the target partition using Disk Management

Since Windows only supports FAT32 and NTFS, so we can format the target drive to FAT32 or NTFS. Please refer to the following content.

Note: ✍ If you want to use the SD card on smart TVs or projectors, you should choose FAT 32; if the target drive is an internal computer drive, you'd better select NTFS. ✍ Once your hard drive is formatted, all data on it will be deleted.

Step 1. Right-click "This PC" on the desktop and select "Manage". In the pop-up window, select "Disk Management" under the "Storage" option on the left.

Step 2. Right-click the target drive, click "Format".

Step 3. In the new window set the "Volume Label", "File system" and "Allocation unit size", then click "OK".

│ Method 2. Use Diskpart to remove write protection

The target disk has been write-protected is another main reason for Windows 11 Disk Management cannot assign drive letter. When the target disk is write-protected, we must remove write protection from the drive , beacause we cannot make any changes to it. Here, we will describe in detail how to use Diskpart to remove the read-only.

Step 1. Press "Windows + R", then type "diskpart" in the "Run" window and press "Enter".

Step 2. Type the following commands and press "Enter" after each command.

• list disk (All disks in the computer will be listed.) • select disk n ("n" refers to the number of the target drive.) • attributes disk clear readonly

diskpart remove write protection

Step 3.  After successfully removing write protection, you can type "exit" and press "Enter" to leave Diskpart.

An easier way to solve Disk Management cannot assign drive letter 

How to deal with Windows 11 Disk Management cannot assign drive letter? Although we can format the target drive or remove the write protection, here we would like to recommend a simpler and more convenient disk managing freeware - AOMEI Partition Assistant Standard .

Just remembered I wanted to post something about this. Seems windows 11 does not remember or cant read what a drive's last drive letter and path was in a previous install, when entering OS after formatting and fresh installing. Not really a problem if you know witch drive and volume is witch, [quick rectifications in the drive management and all is set again] But I believe this could be resolved, wasn't a problem in previous installs of Win.

I misread that. I thought by "install", you meant connecting the drive. With installing the OS, yes, drive letters are completely reassigned.

This is the secondary drives? My Win 11 has no problem with this, either internal or external USB things.

Drive letter assignments don't carry over between installs if you changed them from their defaults. I believe Windows goes through storage drives in some order (it's always the same order per motherboard) and assigns the first available letter.

itrip said: I know for a fact that my drive letter remained the same with a fresh win 10 install and now it's not like that with win 11. Why else do you think I'm posting about this, not just for the fun of it but because it struck me odd. Click to expand...
USAFRet said: 'Can get reassigned' is not the same as 'always gets reassigned'. A drive that was D before will probably be D again. Especially if plugged into the same port. But this is not guaranteed. Click to expand...
itrip said: if that's a fact then it's still best method to know beforehand what data is on witch storage hardware when doing a format and fresh install. Click to expand...
USAFRet said: Yes. You should always know what is on which drive. Before I do any OS reinstall, I make a careful note of what is where. Often, changing the Volume name to contain the old drive letter. For instance, I lebel the drives/and its partition by the drive type. 660p, or 860EVO I might change that to 660p_H and 860EVO_L The H and L are the drive letters they had before the OS reinstall. After the install, I can assign them the old letters. Of course, the contents of those secondary drives won't be touched during the install, because those drives are offline during that process.

You know windows is still doing this odd behavior, doesn't matter anyway because I have readapted. Just noticed this again the other day, It's not like I'm uninstalling the hardware and putting it in a new pc or am I? ( could be seen that way cause the pc gets a new Device ID every time), well any ways I haven't installed windows 10 again, so I cant know If with that OS such changes would not accour.

Additional FAQs

Is it safe to change drive letters.

Changing drive letters is not a problem in itself. But if your computer needs to run a file that’s written in that very drive, you might have an issue. It’s not just for any reason that Windows warns you before changing a drive letter.

Generally, it’s not recommended to change drive letters unless that would help solve a specific issue. For example, if your Windows Explorer doesn’t recognize an external device under a certain driver, it’s okay to change its name.

There are some drives you can change the letters of without consequences. For example, to a partition that has files you rarely use. Also, you can change an external drive’s letter without problems.

To change the drive letter or paths in Windows, just follow these simple steps:

  • Right click on Computer or This PC and select Manage to open and access Computer Management Console.
  • Disk Management Console display the details of all available volumes and disk drives in the computer configuration in the right pane.
  • Then click on Change button.
  • Click Yes to confirm.

Beside, the drive letter for the system volume or boot partition cannot be modified or changed. And if you install some applications or programs in the drive that you have just changed the drive letter, they may not functioning properly after the change due to the possibilities that the programs will also refer to the specific drive letter or original path used when installation as environmental variables.

Do not assign a drive letter or drive path

Windows Drive Manager

In which case is it usefull? In which cases shouldn't it be used?

Is it good for a drive, where I only want to copy data to and from in Explorer?

  • Unclear : What are you doing? Some screenshots will help. –  harrymc Feb 24, 2019 at 12:31
  • @harrymc I've added an screenshot. I added an new external harddrive to my computer, which I will remove and add from time to time –  Timothy Lukas H. Feb 24, 2019 at 12:39

It means that it will not give it a drive letter. It will format the drive but it will not appear with a drive letter in Explorer.

If you want to copy files to the drive using Explorer then you will need to assign a letter to it. That you don't intend to use other programs to access it is irrelevant.

Whats the use of this function then?

You might want to assign a letter later, or intend to format the drive before moving the disk to another machine without using it on the current machine. It's just telling Windows that you don't want it visible yet for whatever reason.

  • Thank you. Whats the use of this function then? When I can't use the drive at all, I can simply leave it "Unallocated" –  Timothy Lukas H. Feb 24, 2019 at 12:40

What is the use of "change drive letters and paths" in disk management?

Report abuse.

Carlos Atashian

Change drive letters is used when you want to customize to your own taste it.

For example, I always set my DVD drive to "V:".

Sometimes it can be used when Windows y itself does not assign a letter to an external drive or you want it to have a fixed drive letter every time you plug it in.

Google’s Gemini is now in everything. Here’s how you can try it out.

Gmail, Docs, and more will now come with Gemini baked in. But Europeans will have to wait before they can download the app.

  • Will Douglas Heaven archive page

In the biggest mass-market AI launch yet, Google is rolling out Gemini , its family of large language models, across almost all its products, from Android to the iOS Google app to Gmail to Docs and more. You can also now get your hands on Gemini Ultra, the most powerful version of the model, for the first time.  

With this launch, Google is sunsetting Bard , the company's answer to ChatGPT. Bard, which has been powered by a version of Gemini since December, will now be known as Gemini too.  

ChatGPT , released by Microsoft-backed OpenAI just 14 months ago, changed people’s expectations of what computers could do. Google, which has been racing to catch up ever since, unveiled its Gemini family of models in December. They are multimodal large language models that can interact with you via voice, image, and text. Google claimed that its own benchmarking showed that Gemini could outperform OpenAI's multimodal model, GPT-4, on a range of standard tests. But the margins were slim. 

By baking Gemini into its ubiquitous products, Google is hoping to make up lost ground. “Every launch is big, but this one is the biggest yet,” Sissie Hsiao, Google vice president and general manager of Google Assistant and Bard (now Gemini), said in a press conference yesterday. “We think this is one of the most profound ways that we’re going to advance our company’s mission.”

But some will have to wait longer than others to play with Google’s new toys. The company has announced rollouts in the US and East Asia but said nothing about when the Android and iOS apps will come to the UK or the rest of Europe. This may be because the company is waiting for the EU’s new AI Act to be set in stone, says Dragoș Tudorache, a Romanian politician and member of the European Parliament, who was a key negotiator on the law.

“We’re working with local regulators to make sure that we’re abiding by local regime requirements before we can expand,” Hsiao said. “Rest assured, we are absolutely working on it and I hope we’ll be able to announce expansion very, very soon.”

How can you get it? Gemini Pro, Google’s middle-tier model that has been available via Bard since December, will continue to be available for free on the web at gemini.google.com (rather than bard.google.com). But now there is a mobile app as well.

If you have an Android device, you can either download the Gemini app or opt in to an upgrade in Google Assistant. This will let you call up Gemini in the same way that you use Google Assistant: by pressing the power button, swiping from the corner of the screen, or saying “Hey, Google!” iOS users can download the Google app, which will now include Gemini.

Gemini will pop up as an overlay on your screen, where you can ask it questions or give it instructions about whatever’s on your phone at the time, such as summarizing an article or generating a caption for a photo.  

Finally, Google is launching a paid-for service called Gemini Advanced. This comes bundled in a subscription costing $19.99 a month that the company is calling the Google One Premium AI Plan. It combines the perks of the existing Google One Premium Plan, such as 2TB of extra storage, with access to Google's most powerful model, Gemini Ultra, for the first time. This will compete with OpenAI’s paid-for service, ChatGPT Plus, which buys you access to the more powerful GPT-4 (rather than the default GPT-3.5) for $20 a month.

At some point soon (Google didn't say exactly when) this subscription will also unlock Gemini across Google’s Workspace apps like Docs, Sheets, and Slides, where it works as a smart assistant similar to the GPT-4-powered Copilot that Microsoft is trialing in Office 365.

When can you get it? The free Gemini app (powered by Gemini Pro) is available from today in English in the US. Starting next week, you’ll be able to access it across the Asia Pacific region in English and in Japanese and Korean. But there is no word on when the app will come to the UK, countries in the EU, or Switzerland.

Gemini Advanced (the paid-for service that gives access to Gemini Ultra) is available in English in more than 150 countries, including the UK and EU (but not France). Google says it is analyzing local requirements and fine-tuning Gemini for cultural nuance in different countries. But the company promises that more languages and regions are coming.

What can you do with it? Google says it has developed its Gemini products with the help of more than 100 testers and power users. At the press conference yesterday, Google execs outlined a handful of use cases, such as getting Gemini to help write a cover letter for a job application. “This can help you come across as more professional and increase your relevance to recruiters,” said Google’s vice president for product management, Kristina Behr.

Or you could take a picture of your flat tire and ask Gemini how to fix it. A more elaborate example involved Gemini managing a snack rota for the parents of kids on a soccer team. Gemini would come up with a schedule for who should bring snacks and when, help you email other parents, and then field their replies. In future versions, Gemini will be able to draw on data in your Google Drive that could help manage carpooling around game schedules, Behr said.   

But we should expect people to come up with a lot more uses themselves. “I’m really excited to see how people around the world are going to push the envelope on this AI,” Hsaio said.

Is it safe? Google has been working hard to make sure its products are safe to use. But no amount of testing can anticipate all the ways that tech will get used and misused once it is released. In the last few months, Meta saw people use its image-making app to produce pictures of Mickey Mouse with guns and SpongeBob SquarePants flying a jet into two towers. Others used Microsoft’s image-making software to create fake pornographic images of Taylor Swift .

The AI Act aims to mitigate some—but not all—of these problems. For example, it requires the makers of powerful AI like Gemini to build in safeguards, such as watermarking for generated images and steps to avoid reproducing copyrighted material. Google says that all images generated by its products will include its SynthID watermarks. 

Like most companies, Google was knocked onto the back foot when ChatGPT arrived. Microsoft’s partnership with OpenAI has given it a boost over its old rival. But with Gemini, Google has come back strong: this is the slickest packaging of this generation’s tech yet.
