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 can not be written to a portion of the tape that 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, you must move to
the EOD area before writing data onto the cartridge.

SCSI Commands Supported by WORM Drives

WORM drives support the same SCSI commands 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.”

AIT WORM-compliant Software

To find out whether your backup application is AIT WORM compliant,
contact the manufacturer of the software.

Notes

• Sony cannot accept liability for data written onto a WORM cartridge that

is lost as a result of using this unit.

• Sony accepts no responsibility for any financial damages, lost profits, or

claims made by third parties arising from the use of this product.
