HP LTO Ultrium WORM data cartridges
The HP LTO Ultrium 6650, 3280 and 1840 tape drive includes support for both re-writable and
Write-Once, Read-Many, WORM, data cartridges. WORM cartridges provide an enhanced level
of data security against accidental or malicious alteration of data on the tape cartridge. The WORM
data cartridge can be appended to maximize the full capacity of the tape cartridge, but the user
will be unable to erase or overwrite data on the cartridge. Any attempt to modify a WORM cartridge
to enable writing over existing data will result in the media becoming permanently write protected.
It should still be readable in a WORM drive, depending upon the severity of the tampering, but
no further appended backups will be possible.
WORM data cartridges are clearly identified by their distinctive, two-tone cartridge color. They
can only be used with LTO Ultrium tape drives that support the WORM feature.
To check whether your backup or archive software application supports WORM cartridges, refer
to the following website:
http://www.hp.com/storage/spock .
For information on how your HP LTO Ultrium tape drive and WORM cartridge can help your
business meet Information Lifecycle Management and regulatory compliance requirements, please
refer to the HP Business Support Center at:

LTO-6 and LTO-5 Ultrium tape drives and partitioning
The HP LTO–6 Ultrium 6650 tape drive supports up to four tape partitions, when used with HP
LTO–6 Ultrium 6.25 TB RW cartridges. The HP LTO–5 Ultrium 3280 tape drive supports two tape
partitions, when used with Ultrium 3 TB RW cartridges. Tape partitioning is not supported with
WORM cartridges or with earlier generations of cartridge. It is not supported on earlier-generation
tape drives. If you insert a partitioned tape into a tape drive that does not support partitioning, it
will be ejected.
To check for the latest information about support for partitioning and any required firmware
upgrades, go to
http://www.hp.com/support/downloads . Refer to your backup application's
documentation for information about creating and using partitions on the tape drive.
LTO-6, LTO-5 and LTO-4 Ultrium tape drives and encryption
The HP LTO-6, LTO-5 and LTO-4 tape drive includes hardware capable of performing data
encryption at full speed while writing data, and decrypting when reading.
