IBM 3590 Scsi Bus Problems, Fibre Channel Problems, Tape Winds Completely Out of the Cartridge

Replacement of the leader block is a temporary repair. It allows the operator to insert the cartridge, with the file-protect selector (see item ) set to the file-protect position, once. This, in turn, allows the data to be copied to a new cartridge. After you repair the leader block and recover the data, do not use the cartridge again.
