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, 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." 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. 27

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, move to the EOD
area before writing data onto the cartridge.
