Clear Data
Erases all data on the disk but leaves the disk label intact. Clear Data does not erase the FIR data in
the CE sector, the volume label, the boot sector, or the spare tracks table. After a Clear Data
completes or is cancelled, the disk drive is not usable until you restore the file system by using the
SCF command Alter Label.

Down.
Replace

Reset Backup Path
