Getting a drive letter to "stick"

I have an external 2TB WD that I use to copy files to. It needs the drive designation to be Z: When I plug it in, Windows Server assigns it G: I
go to manage my computer and reassign it to Z: When I disconnect and reconnect it is back to G:<o:p></o:p>
Suggestions?<o:p></o:p>
Thanks<o:p></o:p>

Hi,
According to my test, when a drive letter is assigned to a USB device, it will add/change the key below. So please have a try to backup the key HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices in regedit first, change it to Drive Z and delete the value:
\DosDevices\G:
Refresh and see if \DosDevices\Z: is created and G: is removed correctly.
Reconnect the USB device and see if issue still exists.

Itunes sees IPOD but I cannot get a drive letter to use as a hard drive.

I set disk use enabled but every time I unplug and replug the IPOD back in the check box is unchecked.
What system does windows/IPOD use to mount the IPOD and get a drive letter? I am using a customized version of XP and I want to make sure I did not delete a particular system in XP.

I don't think you'd be able to shut off the Logical Disk Manager service, which is what Windows uses to assign drives letters to mounted volumes. It is possible that it's not loading correctly or automatically, however.
Open up My Computer without the iPod connected and write down all the drive letters you see (for Hard Disk Drives, Devices with Removable Storage, and Network drives, if applicable). Then connect the iPod and double check just to verify there aren't any new drives present. Now right click My Computer and click Manage. In the Computer Management window, click on disk management on the left side. In the upper portion on the right side, look to see if there is a volume that matches your iPod in capacity (will be off by a couple of gigs, likely) but that doesn't have a drive letter. Right click that volume, and hit "Change Drive Letters and Paths" and then attempt to add a drive letter to the device, taking care to note that you are using a drive letter that is not on your list you wrote down earlier. It's usually best to leave some room between the iPod and the last used drive letter... for example, if you have A, C, D, E, and F drives, assign the iPod letter M. Then check to see if the M drive is showing up in My Computer, and right click it and eject it if it is. Then restart the computer.

Ipod fails to get a drive letter

my ipod nano does not get a drive letter when connected. after assigning it a drive letter through disk management in windows xp, it behaves fine until itunes shows up and starts updating it. at this point, the ipod loses the drive letter. when i try to assign it a drive letter, the old drive letter doesn't show up in the list.
it was working fine until recently. not really sure if its an ipod problem or a windows problem. any ideas?
thanks

How to get the drive letter of a Volume using command prompt

Using windows command line tools i want to get the drive letter of a volume, by specifying its volume number.
For example i have a HDD with 2 volumes: Volume-0 and Volume-1
I want to set a Variable say 'Letter'=<Drive Letter> such as
SET Letter=<Command> <Volume Number>
Is there any command which can do this for me...
Thanks...

Hi,
You can use the diskpart tool to assign a drive letter to the drive by specifying the volume's number.
1.Open Command Prompt.
2.Type:diskpart
3.At the DISKPART prompt, type:list volume
Make note of the number of the simple volume whose drive letter you want to assign, change, or remove.
4.At the DISKPART prompt, type:select volume n
Select the volume, where n is the volume's number, whose drive letter you want to assign, change, or remove.
5.At the DISKPART prompt, type one of the following:assign letter=L
Where L is the drive letter you want to assign or change.
For more detailed information, you could refer to the article below:
Assign, change, or remove a drive letter

Cannot connect to iTunes or get a drive letter in windows

Please Help!!
The Problem
I have a 30gb iPod w/video. It was woarking but now iTunes for windows will not see it and it doesn't show up in My Computer as a drive either. It does show up on the task bar as a USB Mass Storage Device and the iPod goes to "Do not Disconnect" mode but windows doesn't assign a drive letter. iPod updater will also not find the iPod.
Things I have tried
I connected the iPod to another PC and it worked so it is definatley a software problem. I updated the iPod with the latest iPod updater anyway.
I tried another iPod on the problem PC (60gb iPod w/video), same prob.
I tried a different cable on the problem PC.
I uninstalled iTunes and iPod software on problem PC and intalled the latest versions.
I reinstalled Service pack 2 for windows.
With the iPod connected I removed the USB Mass Storage Device driver from the device manager so that windows would redetect and reinstall the appropriate drivers.
Windows redetected the following
iPod
USB Mass Storage Device
ipod usb device
disk drive
None of the above has changed tthe original problem in any way.
Please if somebody has a fix please post.
Thank you so much
Nicolas

The way to correct the disabled phone is to use this support document http://support.apple.com/kb/ht1212. However, you are going to need a SIM in the phone to activate it again. Even if you do not intend to use it as a phone, it will still need a SIM for the activation process. It can be an SIM that is no longer connected to an account.
I'm sorry, I missed part of the message. Yes, restore is the only option.

New-Partition assignes driver letter to mount point after reboot.

Trying to create a series of mount points using powershell on Server 2012 R2. When I have used diskpart in the past I could initialize the disk, create a partition, format a volume and assign a mount point without assigning a driver letter to the drive.
When I try to do the same thing in Powershell on Server 2012 R2, everything looks great until I reboot. Every partition I created and assigned as a mount mount gets a driver letter added to it... I am using mount points to avoid drive letters. Is there a way
to prevent this behavior. The following is an example:
Get-Disk 3 | Initialize-Disk -PartitionStyle GPT
Get-Disk 3 | new-Partition -UseMaximumSize -AssignDriveLetter:$False | Format-volume -confirm:$False
Add-Partitionaccesspath -DiskNumber 3 -Partition 2 -AccessPath c:\someFolder
Everything looks good at this point with no driver letter assigned. Rebooting adds a driver letter to the volume with no impact on the mount point... Is there a way to suppress the driver letter assignment?

Figured it out... It appears that this part works fine:
Get-Disk 3 | Initialize-Disk -PartitionStyle GPT
$Part = Get-Disk 3 | new-Partition -UseMaximumSize -AssignDriveLetter:$False
$Part | set-partition -NoDefaultDriveLetter:$True
$Part | Format-volume -confirm:$False
If you look at the output of Get-Partition the NoDefaultDriveLetter value is TRUE. After running Add-PartitionAccessPath it changes to FALSE. You can set it back with the Set-Partition command:
Get-Partition -DiskNumber 3 -Partition 2 | add-PartitionAccessPath c:\SomePath -passthru | set-Partition -NoDefaultDriveLetter:$True
I had a bunch of them to do so I used the following:
Function Config-Disk {
[cmdletbinding()]
Param(
[INT]$Disk,
[INT]$Partition = 2,
[String]$Label,
[String]$MountPoint
Get-Disk $Disk | Initialize-Disk -Partitionstyle GPT
Get-Disk $Disk | New-Partition -UseMaximumSize |
Format-Volume -FileSystem NTFS -NewFileSystemLabel $Label -Confirm:$False
Add-PartitionAccessPath -DiskNumber $Disk -PartitionNumber $Partition -AccessPath $MountPoint -Passthru |
set-Partition -NoDefaultDriveLetter:$True
MD "c:\SomeLocation1"
MD "c:\SomeLocation2"
Config-Disk -Disk 3 -Label "SomeLabel1" -MountPoint "c:\SomeLocation1"
Config-Disk -Disk 4 -Label "SomeLabel2" -MountPoint "c:\SomeLocation2"

Modify link to not reference a drive letter

Hi,
I am trying to edit a link in a pdf (to another PDF) where these files reside on a CD. Given that many people have a different drive designation on their computers I wanted the link to be something like:

Any thoughts?
I am using Window XP Adobe Acrobat 8 Professional.

$drive = (New-VHD -path $vhdpath -SizeBytes $size -Dynamic | `
Mount-VHD -Passthru | `
get-disk -number {$_.DiskNumber} | `
Initialize-Disk -PartitionStyle MBR -PassThru | `
New-Partition -UseMaximumSize -AssignDriveLetter:$False -MbrType IFS | `
Format-Volume -Confirm:$false -FileSystem NTFS -force | `
get-partition | `
Add-PartitionAccessPath -AssignDriveLetter -PassThru | `
get-volume).DriveLetter
Dismount-VHD $VHDPath
function MountVHD ($VHDPath)
Mount-VHD $VHDPath
$drive = (Get-DiskImage -ImagePath $VHDPath | `
Get-Disk | `
Get-Partition).DriveLetter
"$($drive):\"
Get-PSDrive | Out-Null # Work around. some times the drive is not mounted
Refer to:
Creating Data VHD using PowerShell
You can also assign driveletter via powershell.
To mount a dismounted VHD, you will get the drive letter:

How do I get Lightroom to find photos on a USB Drive when the Drive letter changes?

THis is probably a simple question but I keep getting stuck. I ha
ve my catalog and some images on my laptop hard drive, but the majority are on
an external USB drive. Sometoimes the drive gets assigned
E:, F;, or G:, and when it cahnges, the catalog says the phots are missing. How do I get
Lightroom to find the photos again?
Tom Barnwell

The quick fix is to click on the folder containing the missing files and choose "update Folder Location" then find the folder on the USB drive. The longer term and fix you should apply is to set Windows to always give the USB the same drive letter. You can do this through the XP Disk Management application in Computer Management (Control Panel applet). The following screenshot is for XP, but Vista and Win 7 will something similar which can be accessed via Administrative Tools (see second screenshot).

Did you fails to do this?
If so, not good, you can redownload some itunes purcahses in some countries:

Wrong Drive Letter Assignment

This issue caused about 8 hours of grief with trying to get the new iPod to work.
The short of it is, when the iPod is connected, Windows was assigning a drive letter to it that was already in use, Drive F. It also happens that this drive mapping pointed to the Network Share where my music and photo files were. Therefore, iTunes was trying to put the files back to the same place.
No errors were displayed and operations continued along like nothing was wrong. iTunes indicated that all my files were on the iPod but the iPod was bare.
The fix was to go to Manage computer (right mouse click on My Computer, select Manage) then in Disk Management you can reassign drive letters to connected devices. Select the iPod device and give it an unused drive letter. Windows will use that letter in the future when connecting the iPod.
I spent the 8 hours resetting, reinstalling and rebooting everything in sight until I explored using theiPod as an external drive and noticed that it wasn't showing up in My Computer as a mapped drive.
Hopes this hopes helps solve it for someone else.

You've described the issue well, but this is a long-time known issue, documented on the Apple support page (http://docs.info.apple.com/article.html?artnum=93499). Windows has a tendancy to forget about Network mapped drives when assigning new physical drive letters.

How do I find out about the driver letter of a usb drive by script, given the DeviceID

After changing disc drive letter iTunes no longer recognizes Cd's

I changed my disc drive letter from G to A, & now iTunes no longer recognizes Cd's but when I change it back to G, iTunes recognizes Cd's again.
I've done a full reinstall of all apple software components but still won't recognize disc drive set to drive letter A even after reinstalling iTunes with drive set to letter A.
I've looked at all the help documents & nothing relates to this particular scenario.

I've done a full reinstall of all apple software components but still won't recognize disc drive set to drive letter A even after reinstalling iTunes with drive set to letter A.
Traditionally, in Windows, the A drive letter has been reserved as one of the two floppy drive letters (It's actually the letter reserved for the boot floppy ... which is why most floppy drives on relatively-modern-machines-that-still-have-a-floppy-drive are B drives, since the C hard drive is usually the boot drive.)
So I'm not surprised you're getting erratic sorts of behavior from a A:\ drive that isn't a floppy. If you need to change your optical drive letter, try perhaps an H or higher letter.

Windows 8 does not remember secondary SATA hard drive letter

So, I bought an HP Pavilion with a 1TB HDD with Windows 8 installed. I burned the recovery disks, wiped the 1TB (Seagate) drive and installed a 250GB (WD) drive. I installed the WD as the primary boot and OS, and formatted the Seagate as a basic drive for
storage. I reinstalled from the recovery disks, and the OS went exactly where I wanted it to, but the Seagate doesn't list in the My Computer display. It does appear in the BIOS, and it does appear in Disk Management.
I searched the internet and found the tips about using Disk Management to assign a drive letter to the second drive. SUCCESS! Or so I thought. I can see the second disk in disk management, and can successfully assign a drive letter so that the drive appears
in My Computer; but after any/every reboot, I have to go through the same process over and over and over again. Windows 8 is not "remembering" the drive letter settings for this particular drive.
It doesn't seem like a big deal, but this drive is intended as a shared drive for the "Homegroup" so that everybody can use it as storage. Not everybody in the small office is familiar or comfortable with going through this, so I need the system
to "remember" the disk settings all of the time.
The 1TB Seagate has the following properties:
Disk type - Basic
Partition style - MBR
File system - NTFS
Does anyone have any ideas? Suggestions?
Thank you!

Hi alcisco70,
The drive letter miss after restarting the computer, right?
I would like to suggest you update its driver firstly, and then do the following:
open a command prompt with administrator privileges, then type:
Diskpart
List disk (you will get detail disk info, if you only have one disk, it will show disk 0)
Select disk 0
List volume (you will get detail volume info)
Select volume # (change # to corresponding number)
then enter:
attributes volume clear hidden
After that, restart the computer and reassign the drive letter to that volume. And navigate to the path below:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\VolumeInfoCache
Which lists all the current drive info. check if there is any conflict.

ITunes can't see my songs. Drive Letter Change.

I have over 10,000 songs in my iTunes library. They all have a path that originates from my drive L. This is my external hard drive. The drive was shut off, as it has been many times in the past, and when it was turned back on, it was all of a sudden drive M.
Now iTunes cannot find anything in my library. I tried the Disk Manager in Win7 to reassign the drives letter back to L but it won't let me do it because the final step is to pick the drive's new letter assignment from a drop down menu, and "L" is not available.
Can anyone help me with this. Is my iTunes simply just useless from here on out. I'm not deleteing it and starting over again just so the drive letters can switch again.
thank you for any help.

The problem fixed itself -- somewhat. Now, iTunes sees audio CDs. But when I eject them, iTunes doesn't notice. I generally have to open & close the CD tray 2-4 times to get iTunes to notice that I have switched CDs. This is an iTunes problem, not Windows or my Plextor -- only iTunes has any issue with CDs being inserted or switched.
Hey Apple, I really appreciate the lack of support here.
