Change Drive Letter and Paths... greyed out. Can't assign drive letter.

Q: Change Drive Letter and Paths... greyed out. Can't assign drive letter.

I have a drive that has a lot of information on it that I need. A user left our company and all of his files are on this drive. I was handed it and asked to build a VM with all his information on it. When I plug the drive in it loads the drivers and shows
up just fine in Computer Management (shown below), but not in Computer. So I think, ok, I'll just add a drive letter but that option is greyed out and won't let me. The disk is initialized and appears to be healthy. I have gone to device manager and made sure
there were no problems there as well. It was also an external drive so I removed it and made it an internal drive on my machine but got the same results. It shows up in BIOS but obviously can't boot off of it since it is not an OS drive.
Deleting/formatting the drive is not an option. Is there a way to get this drive accessible without that? Deleting it is the exact opposite of what I want done here.

Preferred Solution: Change Drive Letter and Paths... greyed out. Can't assign drive letter.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

That looks like a mac formatted drive, that's why it wont work on your PC. Try installing Paragon HFS+ for Windows.

I am still unable to access my WD 5000H1U external hard drive. It is showing in Device MGR & Disc Management. However when I access Computer it is not showing. When in Disc Management it is there ok but with no drive letter. Right click reveals drop down box but everything is Greyed out. The external HD is up and running ok with blue lights, I have even tried 3 separate USB cables but with no joy. I have checked the drivers and they are up to date...... When i first switched it on it did register ok in Computer but since then nothing. It works perfectly on my Apple laptop. I am running Windows 7 Home edition. Any help would be much appreciated. Lee

A:Change Drive Letter & Paths Greyed out

Has the drive been initialized?

To initialize new disksIn Disk Management, right-click the disk you want to initialize, and then click Initialize Disk.
In the Initialize Disk dialog box, select the disk(s) to initialize. You can select whether to use the master boot record (MBR) or GUID partition table (GPT) partition style.
Note The disk is initialized as a basic disk.

Additional considerations
New disks appear as Not Initialized. Before you can use a disk, you must first initialize it. If you start Disk Management after adding a disk, the Initialize Disk Wizard appears so you can initialize the disk.

I'm just curious, because if we can assign a letter for a drive [for example, C:], then, can I assign a letter to a folder? Because when I save/open a file or anything like that, I can just type the letter of the drive if I want to access a drive, so I wish I could assign a letter to a folder.

All the three partition have the same drive letter.i attach a link showing the picture. all three partitions are dynamic , simple. if i open these drives only the contents of one drive are appeared. another two drive data are not shown in any manner.

i don't want to lose any data from any drive ......
please help me sir...
my windows is installed in c:\ drive which is also dynamic and there are no recent changes.only one change i did which is i shrink dynamic volume 50 GB from 206 GB and again mixed with 206 GB without allocating free space.

and only the c drive is on and d drive is off.but in my other desktop same configuration exist.
please help me...and please don't say change and remove drive letter...........waiting for response

A:changing one drive letter all 3 partitions change to that drive letter

First thing you're going to do is fill in the specs of the desktop whose snips you are showing us.

Then you're going to do the same with the second pc opening a second post with snips. Give it a different title like "Second pc with drive letters the same". Don't forget the snips.

You should not have dynamic disks in either machine. What did you do to accomplish this?

There exists a bevy of spectacular experts on this site that will be happy to help you. But give us ALL the info please.

I lost my Event Viewer, and had to do a repair installation to fix it. Unfortunately, during the repair install, Windows decided to rename my second HD as the D: drive... it was K: before that. Now I cannot access any of my docs, pictures, music, or videos through the normal means... they don't show up in libraries or explorer, and apps like Restorator and Sure Thing (CD labeler) cannot find them. I think that means the paths are broken..?

It won't allow me to rename the HD back into K: (it's not listed as available). I can access the data by clicking Computer > D, and I can see the data is there, but its unusable as of now. Any ideas?

A:Can't change hard drive letter to needed letter

Hello Stevie,

To be safe, you should create a restore point before doing this in case you make a mistake and need to use it to do a system restore.


1. If the K letter is not being used by another internal drive, then you can open regedit and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. In the left pane, Take ownership (step 2 in Option Two of METHOD TWO) of the registry key MountedDevices and "Allow" yourself "Full Control" of it as well.

3. In the right pane of MountedDevices, right click on \DosDevices\K: and click on Delete and OK.

4. Restart the computer to apply. You should now be able to change the second hard drive letter to K.

Hope this helps,

I'm playing with a recently retired server running 32bit Windows 7 Professional. Originally it was configured as RAID 0 with 5 SATA drives. Those drives are gone but I want to install a spare 2TB SATA drive that I have. Using the RAID Management software I have created the drive and it shows the correct configured capacity. I initialized the disk with Disk Management and it lists the disk as online but it doesn't show up in the volume list with a drive letter. My intention is to use the 2TB drive as media storage. Other than combing RAID and Windows 7, what am I doing wrong? Am I better off reformatting everything and reloading Windows?

A:Unable to assign drive letter to newly installed SATA drive.

I have Win 7 home premium on an HP laptop with 4 usb ports. I have 2 Western Digital Elements 1.5 TB drives for backups. If I plug in one of the drives, Win assigns a drive letter, but if I add the second one it doesn't.

To troubleshoot, I've plugged each drive into every usb port on the laptop, and each port reads each drive alone, but if I plug in the second drive while the first is still in, it shoes up in devices but does not get a drive letter. I tried assigning a different drive letter to the device plugged in first, but Win still doesn't assign a letter to the second drive.

Any advice? Thanks!

A:Win 7 doesn't assign drive letter with 2nd Western Dig Elements drive

Did you try to plug them in reverse order (the second drive first and when that's recognized, plug in the first one)

I had to run the WD-DriveManager (which came with the 1TB drive) once to " beat" them into submission

Solved - XP won't assign a drive letter


I just put together a new P4 system runnning Windows XP and tried to add my old HD (Maxtor 80GB) to it. It is jumpered properly as a slave and is recognized by the BIOS. It does not appear in My Computer, however, it is listed in Device Manager. I've tried removing it from Device Manager and reinstalling it with no success.

Under Disk Management, it is displayed as Disk 1 and has a Healthy, Active Partition but just a blank space under Volume. I can't assign it a letter because the 'Change Drive Letter and Paths" option is grayed out when I Right Click on it.

Does anyone have any ideas? I played around with Microsoft's diskpart.exe to try and manually do it, but I don't know how to use it very well and the command line interface isn't very helpful.

Thanks for any advice!

A:XP won't assign a drive letter

Still not showing...

Rick, thanks for the reply. The drive I'm having problems with is not a USB drive, it's an internal HD, so some of the things didn't apply in that link, but I downloaded a third party disk manager (Drive Manager 3.3 by Alex Nolan) and it did not recognize the drive that I'm having problems with at all.

I did some reading on diskpart.exe but still no luck. There's no volume for it, so I can't assign it a letter without that, I guess.

I did make sure 'D:' was available by changing my Zip drive to G:

In drivepart.exe, List Disk shows:

Disk ### Status Size Free Dyn Gpt
--------- ---------- ------ ------ --- ---
Disk 0 Online 37GB 0 B
Disk 1 Online 75GB 0 B

(Kind of confused about the '0 B Free' thing, but shows correctly in Disk Manager)

List Volume shows:

Volume ### Ltr Label Fs Type Size Status Info
------------ --- ------------- ----- ------- ------- -------- -------
Volume 0 E 050910_0753 CFDS DVD-ROM 163 MB
Volume 1 C NTFS Partition 37 GB Healthy System
Volume 2 H Removable 0 B
The only other thing I can think of is doing a Repair Installation of Windows XP, which I'll try as soon as I get my Windows CD back from a friend.

Ok, I recently had a complete system meltdown and had to reinstall windows XP. The reinstall went OK, but I have a problem now that windows will not assign a drive letter to one of my 2 non-raided SATA drives. In looking int he computer management utility under disk management, I find that not only does WinXP recognize the drive, it says it is healthy, active and online. It just doesn't have a drive letter assiciated with it. I have tried right clicking on the drive, but my only option are "help" which is not helpful, and delete partition which I really do not wat to do if it can be avoided. Additionally, I have noticed that the drive letters from B-F are missing. My main HDD is I:\.

If anyone has information on this issue I would very much appreciate it.

A:Xp will not assign a drive letter

When you re-installed Windows, did you specifically ask for it to be installed on I:\ drive, or did it do it itself?

You might consider disconnecting all your drives - except the C:\ drive, and try re-installing Windows.

I have a dual-boot system with Win 7 and XP-pro (on a second HDD). There are two other partitions which I use between both OS's and have Win 7 designations D: for data and E: for setups/backups.

Win 7 has the usual primary,hidden,system,boot partition named WinRE and in windows 7 it is not seen and not assigned a drive letter. So far, so normal.

However, when I boot into XP-pro on the second drive, then unfortunately the WinRe partition is seen, and being the first partition on the 1st HDD, gets assigned drive letter D: That letter cannot be changed, so I can't actually have the same two partitions as D: and E: in both OS's apparently. Or is there a way to make the WinRe partition invisible to XP-pro (currently unchangeable assignment D: ?

A:Want to de-assign a drive letter

I would think you can just right click on it and change the drive letter there. Are you saying you can't right click on D in Disk Management in XP and change it to something like X?

I installed a 80gb IDE hard drive into my other computer to access data on it and Disk Management lists the drive as "Disk 0" but will not let me assign it a drive letter or explore the drive for data. When you right click the drive it has the "Explore" choice grayed out. The only choice is to "Delete Partition...". On the disk right click choices all you have is "Convert to dynamic disk" and nothing else. The disk is the system and boot disk (I believe that is has a single NTFS partition for the entire drive space) from another PC that I don't need anymore and it has an installation of XP Professional 32-bit on it and the PC that I installed it too is XP Professional also but it is 64-bit OS. I tried a few commands in the command line utility DISKPART but none of those helped me either. I have installed foreign disks in XP many times in the past and have never seen this. Oh, also tried "Rescan Disks" from the Action menu and still no go. Any Ideas?

My son's original computer quit suddenly -- either the mobo or the CPU died. No big deal -- he replaced the machine. But he wants the data on the hard drive from the old machine.

So I installed it in his new machine for him as a second hard drive. That was the easy part.

The new machine's BIOS sees and recognises the drive, and so does the Windows hardware management services on the new computer. The drive is visible in both the Device Manager and the Disk Management utility. But Windows will not assign a drive letter to it, so it does not come up in My Computer. What's on it is not accessible.

The BIOS correctly identifies the drive as a 40GB Samsung SP4002H. Disk Manager shows it as a basic drive with a capacity of 37.3GB with 19.64GB free in a NTFS format. It is marked Active and Healthy. Drive Manager's Disk Rescan utility has no effect, and the option for re-assigning drive letters for this drive is greyed out. The only available options for this drive are "Reformat" and "Help".

The new system the drive is now mounted in provides IDE connections for both SATA and PATA drives. The Samsung 40GB drive is a PATA drive, and is in the Master position on the data cable. A DVD drive is in the slave position. Both are jumpered for CS. The BIOS shows the Samsung drive as the Primary Master, the DVD drive as the Primary Slave, and the SATA boot drive as the Secondary Master. There are no other drives in the system.

Hello coffent,

You should be able to use OPTION TWO to see if "R" has already been assigned. If so, then you could use step 4 in OPTION TWO to swap the "R" drive letter with the letter the partition is currently using.

Is it possible to assign a USB flash drive a specific drive letter that would be the same on all computers.

For instance, assign a flash drive the letter X: and if I plugged it in your computer it would also be shown as X:

What I'm trying to do is have a program on the C: drive send its data to the flash drive regardless as to what computer it is plugged into.



A:Assign USB Flash drive letter

No. NT based systems don't actually assign a letter to a drive like DOS did. It will be assigned on a first-come, first-served basis unless the machine has registry settings for a drive letter for that device already. It will then assign the same letter the next time (usually). In fact, NT doesn't need to use drive letters at all.

But it's easy to change in Disk Management.

I've been struggling with this for 3 weeks now and I'm ready to call uncle. I have two HDDs. One is a Seagate 4.0 GB ST34311A and the other was a 30 GB Maxtor HDD. I had the Maxtor HDD set to primary and the Seagate set to slave. Win XP Pro was installed on my Maxtor 30 GB HDD and this worked fine for several years with NTFS file system on the Maxtor and Fat32 on the Seagate. However, my Maxtor HDD became unstable, starting making ominous clicking noises, and on boot up, my computer warned me to "back up and replace it." My Seagate is fine.

I get a 120 GB Western Digital HD, format it, and install it as the primary HDD and the Seagate 4.0 GB as the slave. No new IDE cables, etc., everything exactly the same except a new primary HDD. Now here's the problem. Bios and Windows XP recognizes all drives, however, Windows XP refuses to assign a drive letter to the Seagate drive. It's in Device Manager, which says that the device is working properly. Windows XP can read the size of the Seagate HDD correctly, free space left, etc. however I can't access the drive at all!

Now someone suggested to me it could be the two different file systems, however, this was not problem between my old Maxter 30 GB HDD and the Seagate, so I don't understand why it would be a problem between my Western Digital 120 GB and the Seagate 4.0 GB. Of course, I'm no expert either.

Is it at all possible to assign a constant letter to a drive that will say the same between computers? If not, is there a command line I can run as a .bat file that will set it without having to know the drive letter and manually set it?

A:Assign a static drive letter

The best way is to map a drive to a share and run it on either computer e.g.

@echo off
Net use H: \\computername\sharename /persistent:no

The persistent bit allows the drive letter to be removed when the user logs out and then re-apply when the user logs in again. You can put the script in the startup folder in the user's profile e.g.
C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Ok, I am running windows 98 SE
Dell laptop inspiron 5000
I have one USB port on the unit that is a V.1 USB. I normally connect this port to an external CD burner (F: drive)

I also have a cd drive on the laptop. (D: drive)

I recently puchased a USB 2.0 high spped external hard drive. However, because my USB port was version 1.0 -- Dell told me that it would not support a USB 2.0 high speed external drive device.

So I purchased a Belkin PCMIA USB card that has two V2.0 usb ports.

I have installed the Belkin USB card and my Dell recognizes the card fine. I can plug in my digtal camera in this card and my system assigns a drive letter E: to my camera without any problem.

However, windows 98 won't assign a drive letter to my USB 2.0 High Speed drive when I connect it to the Belkin USB card. Thus I have not been able to use it so far. I can't connect it to the USB port on the back of my Dell because that USB port is v.1 and DELL told me that it can not support V.2 USB devices, which is what my USB 2.0 high speed drive is.

So my question is: What can I do to make windows 98 SE assign a drive letter to my USB 2.0 drive when I connect it to my Belkin USB card?

I have just re-installed Windows (XP). For some inexplicable reason, (the computer has two hard drives) it has re-assigned drive letters. It calls the boot disk drive "E" and the other HD drive "C".

Note that it is booting correctly, which comes as a surprise as I thought it always HAD to boot from drive "C". Looking at the properties shows the boot drive as drive 0 and the other (now called "C") as drive 1.

Can I simply re-assign the drive letters using Disk Manager, or will this cause problems.

Right clicking on the black single partition area brings up seven options (the first five are grayed out): New Simple Volume, New Spanned Volume, New Striped Volume, New Mirrored Volume, New Raid-5 Volume, Properties, Help.

Using CMD with administrator privileges so as to use the diskpart process does not work. Neither "list disk" nor "list volume" shows the plugged-in disk, only shows the SSD integral boot disk. Third party software does show the drive, but apparently offers only a VERY long "repair" process which I'm not quite ready to perform plus I'd need to purchase another high capacity HD to transfer the data onto etc.

Can anyone help? Thanks

Run into an issue with a hard drive showing 3 partitions, but I can't assign a drive letter to it.

Background: It was running Win 7 Pro 64-bit, but was having occasional issues with blue screening. I've pulled the hard drive from that PC and have it hooked to my own (also Win 7 Pro 64) via USB external HD enclosure to run scan disks. The first two partitions I'm accessing fine, but the third one won't give me any options, no matter what I try. Any insight would be great.

EDIT: And sorry, right under where the submenu appears that says "Help", it says "Healthy (Recovery Partition)".

A:Unable to assign drive letter to HD partition?

Hi FuryoftheStars,

First let me tell you how to make a full screen Windows Disk Management screenshot.

Before you take the screenshot, go to the top menu bar and click on the "Show/Hide Console Tree" and "Show/Hide Action Pane" to hide those. Then we can clearly see all the columns in the top listing of the drives. Sometimes that information is necessary.

A sample screenshot with no information obscured/truncated:

Now a straight answer to your query:

The OEM Recovery partition in this case (and in most other cases too) is deliberately of a different Partition Type so that users cannot access it with Windows, meddle with it and spoil the broth. You may change the partition type to the normal type accessible to Windows and then assign a drive letter.( If you want to do it, do it at your own risk .)

If information on it is already available, I do not want to rewrite it . Please see Techno Wizard's last post dated 21 Oct 2013 here Assigning a letter to OEM Partition ( Take only what he says about recovery partition. The hibernation partition is not applicable here.)

(Now on my part ) You can also change the partition type using MiniTools Partition Wizard.( Changing it with diskpart by normal users is a little bit tedious and requires care)

EDIT: You can ascertain the current partition type from the "Properties" page in the first right click menu ( the last in that menu)

Having said all this, whatever problem you had with that ... Read more

Hello !
Is it possible to asign a drive letter to a "digital camera"?

I can't find the option, and can't find any solution on the web

A:Assign a drive letter to digital camera?

What brand and model number is the camera?

My little mp3 player has two different settings for the type of connection, MSC and MTP modes. With one I get the drive letter; with the other one I don't. Essentially it switches the device from using merely a transfer protocol to using a storage protocol.

Of interest:

USB mass-storage device class

Particularly see the part at the bottom under "See also":

Picture Transfer Protocol

I bet if you figure out which mode your camera is in now and switch it to the other one it will work.

I have a partitioned HDD, last time I had to format and reinstall windows xp, my operating system was "C" drive. When I reinstalled windows, the automatic selection was the next available drive letter. Is there a method of pre assigning a drive letter to an unpartitioned drive prior to windows automatically choosing for me. The drive with my operating system is now "F" drive where it used to be "C". Thanks for any advise.

A user needs to use around eight differnet USB flash drive and her computer's drive D is mapping to Network drive which cannot be changed.

When she plug the USB Flash drive_1 which will be assigned to Drive D which cannot be displayed as Drive D is mapping to Network Drive.
It can be viewed normally after changed USB Flash drive_1 to Drive F by administrator.

When she plug USB Flash drive_2 which will be assigned to Drive D again, it can be viewed normally after changed it to Drive F by administrator again.

But when she plug back the USB Flash drive_1. It will be assigned to Drive D again.

As a result,  it won't work  for all USB Flash drives to be assigned with same persistent drive letter F.

- Are there any method to force a USB flash (1 to 8) to always keep the same drive letter F?
- Or make it to keep the same drive letter F for new USB flash which is never used in that computer?
- Or any method to make it to start with Drive letter F instead of Drive letter D?

I was asked by a client to get data off a circa 2004 PC that has a blown Power Supply. I removed the HDD and proceeded with my usual recovery procedure using a drive adapter cable and power supply. The problem is that I can see the drive in the Win7 Disk Manager, but I can't mount the partition. Most of the time I've not had problems with Win7. It usually just recognizes the drive and assigns a letter to the active primary partition. In this case, I can see the partition, it's active and healthy, but I can't assign it a letter. In fact, all options are "greyed out" except "Delete Partition."

I've also used MiniTool Partition Wizard, but without success. Partition Wizard can assign a letter to the partition, which then shows up in Windows Explorer. If you click on the drive letter, you get the "J:\ refers to a location that is unavailable ...." I can explore the partition with Partition Wizard, but I'm unable to access the files.

Here are the Hardware particulars:

Old HDD: 80GB Maxtor HDD ATA, formatted with 76GB primary partition, Active, NTFS, This was the boot drive for a PC

I'm using Win7 x64. The drive is connected to my machine using a SATA/IDE Combo Drive adapter connected to a USB port on my machine. It uses the standard USB to SATA Serial Bridge Driver.

Any help would be greatly appreciated. Even if I'm missing something that would make me say, "Duh!"

Some people come up with a special and specific requirement. And so it is with pkerr. http://www.sevenforums.com/hardware-...ml#post2680332

He wants Windows to assign the same letter for all his external drives which he is using for backups. He will be connecting just one drive at a time.

The solution is simple.

Windows identifies a drive with a Windows unique ID. Each drive in fact has a unique ID.( the general scene)

You give the same unique ID to all the external drives that you want to have the same drive letter and Windows will oblige you by giving the same drive letter when you plug just one drive at a time.


I have two drives one named ZotacBackup and the other GenBackup. Each have their own unique ID and normally these get the drive letters I and J.

Unique ID of ZotacBackup I: is F3 64 5D 07 ( highlighted in green )

Unique ID of GenBackup J: is AB 3E 68 39 ( highlighted in green)

Now I shall change the Unique ID of GenBackup J: to F3 64 5D 07 ( the same as that of ZotacBackup I: using bootice - my favourite program.)

Changing the Unique ID of GenBackup J:


This change will be perceived by Windows the next time you connect the drive.

Now both the drives have the same Unique ID.

I shall plug out the GenBackup J: leaving only the ZotacBackup I: and change its drive letter to R (or any other free drive letter one may want).

Changing Zotac Backup I: to ZotacBackup R: ( Now Windows has associated Drive lette... Read more
