8
. The tape drive erases the firmware on the tape
and rewrites the header in the cartridge memory to change the cartridge to a
valid scratch (blank) data cartridge:
Note: If you inserted an invalid tape cartridge (e.g. Gen 1, WORM media, or
non-FMR cartridge), error code
7
appears in the SCD and the amber
Fault status LED flashes. If you inserted a write-protected cartridge, or
the media has read-only compatibility (e.g., Gen2 media), error code
P
appears in the SCD. Press the unload button. The tape drive unloads the
cartridge and exits Maintenance Mode after the cartridge is removed.
