Cleaning cartridges
You must use Ultrium cleaning cartridges with HP StorageWorks Tape Blades, as other cleaning cartridges
will not load and run. HP recommends the HP Ultrium universal cleaning cartridge (see Table 5 ). Unlike
some earlier Ultrium
cleaning cartridges, the orange-colored HP Ultrium universal cleaning cartridge is
designed to work with any Ultrium drive.

HP Ultrium WORM data cartridges
The HP StorageWorks SB1760c and SB920c Tape Blade include sup po r t for both re-writable a n d
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 do not
have a write-protect slider and 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://h18004.www1.hp.com/products/blades/components/

HP StorageWorks SB1760c Tape Blades and encryption
The HP StorageWorks SB1760c Tape Blade 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 StorageWorks SB1760c Tape Blades 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
When should I use encryption?
Your company policy will determine when you need to use encryption. For example, it may be mandatory
for company con fi dential and fi nancial data, but not for personal data. Company policy will also de fi ne
how encryption keys should be generated and managed. Backup applications that support encryption
will generate a key for you or allow you to enter a key manually.
