Unable to find "D" drive letter from "Chanage Drive Letter"

Hi,

I was building Windows Server 2008 R2 SP1 64bit and created three drives (C, E, F) as drive letter.

I need to change "E" drive letter to "D" drive letter. I mean I do not see the "D" from the pull down menu, so I checked registry and found "\DosDevices\D:". I released the drive letter "D" by renaming it with other drive letter.
Reg location: HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

However, it still nothing changes...

Please advice me how I can assign D drive letter again.


Best regards,
Akii

No D: Drive under "my computer" ?
D is not available probably because it's taken..
maybe you mapped a network drive under d: ?

post back..

try openning a command line and type "subst  d: /d "  and  then try "net use  d: /d "
hope this helps..

The drive letter D is assigned to CD-ROM device already. Right click on it - change drive letter - remove or assign different one.
Then it will be available for selection on your partition.

it is clear in your attached picture that the letter D is assigned to the CD-ROM, so from the disk management, right click the CD-ROM and the change the letter D to another letter. then you can use D for another drive

i would leave it as it is - if not needed for special reasons
the D: letter is assignined to the cd rom by the bios - so why change it?

if you need to change it, use this tool : http://www.uwe-sieber.de/usbdlm_e.html
noxchoGlobal Support CoordinatorCommented:
nobus, why does he need to use third party tool if the same task can be completed with Windows Disk Management?
The asker simply did not see that the drive letter was in use by device. He needs to free it up and assign to the partition he wants.
nobusCommented:
because it will be changed everytime he reboots
noxchoGlobal Support CoordinatorCommented:
Nope. Once assigned it remains the same. It can be changed only if he is using USB drives which are frequently removed.
With internal drives - it remains. I have tested it.
