How to Write Data onto a WORM Cartridge
As with a regular cartridge, there is no limit on how many times data can be
read from a WORM cartridge. When writing data to a WORM cartridge, the
data cannot be written to a portion of the tape that data has already been
written.
When writing data onto a WORM cartridge, it is appended after data that has
already been written onto the cartridge. Accordingly, move to the EOD area
before writing data onto the cartridge.
SCSI Commands Supported by the WORM Drive
The WORM drives support the same SCSI commands that are supported by
non-WORM drives. However, if an attempt is made to write to a portion of a
tape where data has already been written, the following error information is
returned: "Sense Key = 07, ASC = 27h, ASCQ = 00: Persistent Write
Protect" or "Sense Key = 03, ASC = 27h, ASCQ = 04: Write Position Error."
