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).
An error will also be displayed on the Operator Panel.
• Inserting a WORM tape cartridge into a drive that is not WORM capable 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 use the WORM capability of your LTO Ultrium generation 4 or 5 drive, you need to use
a compatible WORM tape cartridge.

Cleaning Cartridge

An LTO Ultrium Universal Cleaning Cartridge is required to clean the tape drive. The
drive itself determines when it needs to be cleaned and notifies the library. When notified,
the library indicates that the drive needs cleaning by turning ON the Clean Drive amber
LED on the front panel of the library and posting a message on the library display.
A tape drive within a library requires the use of a library menu function to either
automatically or manually clean the tape drive. See
IMPORTANT: It is recommended that the drive be cleaned only when it is requested by the
drive.
The Ultrium Universal Cleaning Cartridge is valid for 50 uses. The cartridge's LTO-CM
(Cartridge Memory) chip tracks the number of times that the cartridge is used.
NOTE: The drive will automatically eject an expired cleaning cartridge.

Cartridge Memory Chip (LTO-CM)

All generations of the LTO Ultrium Data Cartridges include a Linear Tape-Open Cartridge
Memory (LTO-CM) chip ( ) , that contains information about the cartridge and the tape
(such as the name of the manufacturer that created the tape), as well as statistical
information about the cartridge's use. The LTO-CM enhances the efficiency of the cartridge.
For example, the LTO-CM stores the end-of-data location which, when the next time this
cartridge is inserted and the Write command is issued, enables the drive to quickly locate
the recording area and begin recording. The LTO-CM also aids in determining the
reliability of the cartridge by storing data about its age, how many times it has been loaded,
and how many errors it has accumulated. Whenever a tape cartridge is unloaded, the tape
drive writes any pertinent information to the cartridge memory.
The storage capacity of the LTO Generation 5 and 4 LTO-CM is 8160 bytes. LTO
Generations 3, 2, and 1 have an LTO-CM capacity of 4096 bytes.
