change the drive letter of a harddisk/cd-drive

[_TAC_]

hello,

i'm looking for something like

http://www.microsoft.com/technet/community...s/scrdfs72.mspx

-------------------

Change the Drive Letter of a Volume

Description

Changes the drive letter of volume D to Q. If you modify this script to change the drive letter of a volume other than D, note that the volume name in the WQL query must include both the colon ( and two forward slashes (\\). Thus drive C would look like this: C:\\. When specifying the new drive letter, however, you only have to include the colon (in the sample script, Q:).

Supported Platforms

Windows Server 2003 : Yes

Windows XP : No

Windows 2000 : No

Windows NT 4.0 :No

Script Code

strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

Set colVolumes = objWMIService.ExecQuery("Select * from Win32_Volume Where Name = 'D:\\'")

For Each objVolume in colVolumes

objVolume.DriveLetter = "Q:"

objVolume.Put_

Next

-------------------

The problem is that the "Win32_Volume" class doesn't exist under xp.

I need something that chances the driveletter for the dvd-rom to z: and the driveletter for the dvd-rw to m: during unattended setup.

thx for help

Try using diskpart. DiskPart is part of the Win2K Server Resource Kit and the Win2K Professional Resource Kit. (Microsoft includes DiskPart as a core utility in Windows Server 2003 and Windows XP.)

diskpart /s CD-ROM.script > diskpart.Log

REM Select the CD-ROM Drive

SELECT VOLUME 0

REM And reset it's drive letter to Z:

ASSIGN LETTER=Z

REM Scan the disks to see the new volumes

RESCAN

EXIT

F:->Z:

----swap_letter.cmd----

mountvol F: /L >%temp%\guid.txt

mountvol F: /D

for /f %%i in (%temp%\guid.txt) do mountvol Z: %%i

del /q %temp%\guid.txt

thx for the fast help.

@Ausmith1 : diskpart looks not very easy to use

@PaulD_ixbt : Your solution is exactly what i am searching for. I can also map my usb-card reader to a path with your script.

----

My configuration:

The cd/dvd-drive is allways the first drive, the cd/dvd-writer is the second one (sec. contr.). Two harddisks are linked at the other controller (pri. contr.).

In one System i have a promise pci controller with the boot harddisk and the data harddisk (pri master + sec. master) and the dvd-drive/dvd-writer are on the onboard one (pri. master + sec. master). The usb-card reader is - of course - at the usb port.

harddisk 1 --> C: D:

harddisk 2 --> E: F:

DVD-Rom --> G: (should be Z:)

DVD-Writer --> H: (should be M:)

USB-Card Reader --> I: J: K: L: (should be mapped to subdirectorys on d:\usb-card\ )

D:\usb-card>dir /b

1-cf

2-md

3-sm

4-sd

D:\usb-card>

(very stupid work to do it by hand each time after a new installation)

Now my next question: how can i reconize the "right" drive for each drive letter?

[tewk_dawg]

Why does this not work in a batch file, yet works line by line in DOS window.

I get "f was unexpected at this time."

I simply want to rename my cdrom to Z when all is said and done.

--start of batch file---

for /f "Tokens=3" %f in ('"echo list volume|diskpart|find /i "rom""') do set cdrom=%f

mountvol %cdrom%: /L >%temp%\guid.txt

mountvol %cdrom%: /D

for /f %i in (%temp%\guid.txt) do mountvol Z: %i

del /q %temp%\guid.txt

--end of batch file---

On a different subject:

Does anyone know how I can put a timer on my version of Windows XP to expire after a certain amount of days. I've thought about a scheduled task that simply renames the password for the local admin account, but it seems to simple and easily detected, I was wondering if this has been discussed before anywhere?
