HP Ultrium WORM data cartridges
The HP StorageWorks Ultrium 1760 and 920 tape drive includes support for both re-writable and
Write-Once, Read-Many, WORM, data cartridges. WORM cartridges provide for an enhanced level
of data security against accidental or m a licious alteration of data o n the tape cartridge. The WORM
data car tridge can b e 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 modif y 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 car tridges are clearly identified by their distinctive, two-tone cartridge color. They can only
be used with Ultrium tape drives that suppor t the WORM feature.
To check whether your backup or archive software application supports WORM car tridges, refer to the
following web site: h

For information on how your H P Ultrium StorageWorks tape drive and WORM cartridge can help your
business meet Information Lifecycle Management and regulatory compliance requirements, please refer

Ultrium 1760 tape drives and encryption
Your Ultrium 1760 tape drive includes 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. HP U ltrium 1760 tape drives use the strongest
version of the industry-standard AES encrypting algorithm to protect your data.
To make use of this feature you nee d:
• a backup application that supports hardware encryption
• Ultrium 1.6 TB media (C7974A or C7974W); no encryption will be performed when writing earlier
generations of tape
