Corrupted Disk Root Directory ([000000])?

» close window

The Question is:

 
How can I repair the damage caused by moving the [000000]directory of a disk,
 without initialising it?
 
The mistake made was as follows:
 
SET DEFAULT DKA100:[VMSINSTAL]
RENAME [-]*.* [.BACKUP]
 
This unintentially moved 000000.DIR to [VMSINSTAL.BACKUP].  The DCL RENAME
 command cannot be used to move 000000.DIR back because there is "nowhere to
 put it".

The Answer is :

 
  First, consider removing access to enhanced privileges available
  to the user(s) involved.
 
  Assuming that the ANALYZE/DISK/REPAIR command and the Freeware DFU
  package cannot repair this corruption, you will likely have to
  initialize a new disk, BACKUP this disk, and selectively (/SELECT)
  restore the contents of the directories on the corrupted disk onto
  the newly initialized disk.
 
  In any event, you will want to perform a full BACKUP of the disk
  before attempting any repairs.
