4. Replace the cluster shared disks.

5. Check the drive assignments through Windows Explorer. The “phantom” drives you see are the original shared disks. These drives cannot be deleted or disconnected from the Windows Explorer.

6. Remove the Registry entries for the phantom disks: a. Use regedit to display the following Registry entry:

HKEY_LOCATION_MACHINE\SYSTEM\CurrentControlSet\Services

\ Clusdisk\Parameters\Signatures

The numbers listed under Signatures are the drive signatures for the former shared disks. Delete these numbers.

b. Reboot the node.

c. Using Windows Explorer, check the status of the disks. There should no longer be any phantom disks and the new shared disks should have the proper drive letter assignments.

The new shared disk signatures are located in the following Registry key:

HKEY_LOCATION_MACHINE\SYSTEM\CurrentControlSet\Services

\Clusdisk\Parameters\AvailableDisks
