Explanation:  Two segments of the volume claim a different directory table one's first block.

Possible Cause:  Two volumes on the server have identical names and a segment from each volume is causing the error.

Action:  Unload the disk driver for the volume that you do not want to rename. Rename the other volume (the volume that is on the hard disk that still has its disk driver loaded). Then load the disk driver that you just unloaded. Mount both volumes.

Possible Cause:  The volume is corrupted.

Action:  If the volume is corrupted, try renaming or deleting the volume.

Warning: If you delete the volume, all data will be destroyed. You will have to restore the data from a backup.

If the problem persists, make sure a volume backup exists. Delete the volume, re-create it, and restore the data from the backup.
