Or install my USB Drive Letter Manager which can assign a drive letter for USB and firewire harddisks without affecting other types of storage devices. This feature is called AutoMount and can be switched by means of the DiskPart tool: Open a commandprompt, enter diskpart, on the DiskPart prompt enter automount to see the current state or automount enable to enable it. This is up to the administrator because otherwise SAN (Storage Area Network) drives might be mounted accidentally.

Windows Server Enterprise and DataCenter Edition do not assign drive letters to new fixed drives (USB and Firewire disks are usually 'fixed').

Partitioning can be done in the Windows Disk Management (right click My Computer -> Manage -> Disk management) or New external drives are often unformatted and unpartitioned. USBDLM fixes this when configured appropriately. The mapping of the network drives fails when their drive letter is in use.

In general the problem persists when an external drive is attached before the user logs on.

But even Vista and Windows 7 assign a network letter to a new local drive if there is no other one available. Another hotfix shall fix this for XP too: XP with SP3 will assign E: anyway, the USB drive is 'hidden'. Remove the USB drive, create a network drive at E: and reattach the the USB drive again. What the SP3 did not fix is this scenario: Letters C: + D: used for local drives, E: for a USB drive. Meanwhile a hotfix is available (WindowsXP-KB297694-x86-ENU.exe) and the XP Service Pack 3 fixes the problem too. Or let my USB Drive Letter Manager change the letters of USB drives for you.Ī problem. So change the network drive's letter to a higher one to get the lower ones available for external drives. But for each new drive you have to change the drive letter again and it's no solution to assign a letter again to a different external drive because XP can save exactly one assignment per letter. The external drive is invisible and unaccessible then until its drive letter is changed in the Disk Management (right click My Computer -> Manage -> Disk management) or by my commandline tool ReMount. If there is a network drive on the first available local letter then XP assigns it again to a new external drive. In the context 'System' where the Mount Manager assigns drive letters such drives are not visible offhand. Since XP Network and Subst drives are no more global, they exist in the context of the user who created them only. The volume should immediately get a drive letter assigned then.ĭrive Letter Conflict with Network or Subst Drives For instance if you want to remove the hidden attribute from volume 13: The attributes are shown in the right-most column. So, on a MBR disk with multiple partitions, if you set the hidden attribute to any volume they disappear all. So, when a GPT drive is turned into a MBR drive and the old GPT entries at LBA2 are not clensed then there is a 50:50 chance that the MBR partition is seen as hidden and/or read-only.įurthermore they did it all wrong: Even diskpart pretends to set the attributes per volume it reads and writes them all to the same place and so does Windows. But attributes are not in the usual place, instead they are written 32 bytes early, where the unique parition GUID belongs in a real GPT partition table.

It is written into the third sector on disk (LBA2) as an rudimentrary 'Basic Data' GPT partition entry. The MBR partition scheme does not have such attibutes but Microsoft fiddled in something similar: By means of the diskpart command-line tool even a MBR partition can get a hidden (and read-only) attribute. The GPT partition scheme knows a hidden attribute which prevents a partition being turned into an active storage volume. Microsoft TweakUI under My Computer -> Drives. Windows can be configured to hide drive letters in the Windows Explorer.
