WORM Media Errors
The following conditions cause WORM media errors to occur:
• Information in the servo manufacturer's word (SMW) on the tape
must match information from the cartridge memory (CM) module in
the cartridge. If it does not match, a media Error Code 7 will post on
the drive's single-character display (SCD).
• Inserting a WORM tape cartridge into a drive that is not compatible
with WORM causes the cartridge to be treated as an unsupported
medium. The drive will report a media Error Code 7. Upgrading the
drive firmware to the correct code level will resolve the problem.
Requirements for WORM Capability
To add WORM capability to your Quantum LTO Ultrium 6 drive(s), you
need to use either Quantum Ultrium 6 2500 GB WORM tape cartridges
or Quantum Ultrium 5 1500 GB WORM tape cartridges.
Cleaning Cartridge
A specially labeled Quantum LTO Ultrium Cleaning Cartridge is used to
clean the drive head. The drive itself determines when a head needs to
be cleaned. It alerts you by the SCD flashing a C. To clean the head
manually, insert a cleaning cartridge into the tape load compartment.
The drive performs the cleaning automatically. When the cleaning is
finished, the drive ejects the cartridge, and the SCD will be blank.
Note: The drive will automatically eject an expired cleaning cartridge
without running the cleaning process. Replace the expired
cleaning cartridge with a new cleaning cartridge and insert it
into the drive.
The Quantum Cleaning Cartridge is valid for 50 uses. The cartridge's
LTO-CM chip tracks the number of times that the cartridge is used.
Caution: After 50 uses, the cleaning cartridge expires. It is no longer
usable, and must be replaced
