The UNSCRATCHVOL command unscratches a volume that was previously scratched and is in the SCRATCH state. The only time you would use this command is when you have unintentionally scratched (erased) a volume that has necessary information on it. This command allows the user to undo the effects of a SCRATCHVOL command.
