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 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 Ultrium tape drives that support the WORM feature. To check whether your backup or archive software application supports WORM cartridges, refer to the following web site: http://www.hp.com/go/connect. For information on how your HP Ultrium StorageWorks 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: http://www.hp.com/go/bizsupport. 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 Ultrium 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 need: • 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 60 Use the correct media

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 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 identi
fi
ed by their distinctive, two-tone cartridge color. They can only
be used with Ultrium tape drives that support the WORM feature.
