LTO Ultrium WORM data cartridges

The LTO Ultrium 6650, 3280 and 1840 tape drive includes support for both rewritable 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.hpe.com/storage/buracompatibility
For information on how your LTO Ultrium tape drive and WORM cartridge can help your business
meet Information Lifecycle Management and regulatory compliance requirements, refer to the
Hewlett Packard Enterprise Support Center at: http://www.hpe.com/support/hpesc

LTO-6 and LTO-5 Ultrium tape drives and partitioning

The LTO-6 Ultrium 6650 tape drive supports up to four tape partitions, when used with LTO-6
Ultrium 6.25 TB RW cartridges. The 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.hpe.com/support/downloads. Refer to your backup application
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 LTO-6, LTO-5, and LTO-4 tape drives include hardware capable of performing data encryption
at full speed while writing data, and decrypting when reading.
Encryption is the process of changing data into a form that cannot be read until it is deciphered,
protecting the data from unauthorized access and use. LTO-6, LTO-5 and LTO-4 tape drives
use the strongest version of the industry-standard AES encrypting algorithm to protect your data.
