SBS 2008 - Drive Letters for USB Hard Drives RRS feed

  • Question

  • Setting up a backup for a user, 5x Daily rotating USB Hard Drive.

    The network has F: mapped and in a logon script.

    When I plug a USB Drive in Windows automatically gives it F: - This should not occur, why is it?

    So I go ahead and change the assigned letter of each drive one by one to say Z: or whatever I want (first I tried G:).

    Once I've gone through and set the 5, I plug the first back in and it will now receive either F:, G: or Z:.

    To be clear I've plugged them each in individually (only one lead to do so with) and confirmed they have the letter assigned before removing. The backup software I am using (BackupAssist 6.4.1) works a lot smoother if the drives are all the one letter (and I don't want the user seeing "Completed with Minor Warnings" because the drive letter is wrong).

    So, why is Windows assigning a letter to a unique drive, then later on assigning a completely different letter to that same drive?

    Edit - Yes I have removed the other letter assignments from the drive - as in in disk management I have "changed" the drive letter assignment, not added extra ones.

  • Hi,

    Have a try to remove the 5 USB devices in Device Manager so that Windows will reinstall the driver of these devices. Check if issue still exists.

  • Disconnect all drives and run mountvol /R.

    Let me know if it works

    Apart you can use mountpoint instead of drive letters as drive letters are never guaranteed to be unique.

    To Create a mountpoint

    md c:\mnt1

    diskpart> sel vol <vol>

    diskpart> assign mount=c:\mnt1

    use c:\mnt1 as reference,
