change drive letter greyed out
Posted on 2009-07-01
Hi, I have a problem with disk management on an XP Pro machine
Under Disk Management console, it shows the volume names but no letters, if I click change drive letters and paths, only add is available. Drive letters already taken.
All drives are available in file explorer.
diskpart.exe allows me to assign a drive letter to the drive (USB external western digital, or memory stick). If I change the USB drive to another letter, it changes in file explorer, but still the same in disk management console, change not available.
mountvol.exe shows correct key and drive letter assigned, but diskpart select volume does not show a drive letter attached.
The problem surfaced when norton 360 was installed and tried to do a backup. only available items were the CD burner and external web based backup. No usb devices, or local storage available.
I feel there might have been some corruption in the registry, so examined /hkey_local_machine/system/mountedDevices and removed volume ID for usb and dosdevices\E: from there. rebooted and still the same?
Any thoughts as to where else I might look in either registry or services section. I couldn't see any services that should be running as disabled, or not running.
Bit stuck on this one!
