HP ESL E-series Tape Libraries - Manual (Page 20)

Ultrium tape cartridges
The Ultrium 960 and Ultrium 1840 include support for both rewriteable and Write-Once, Read-Many
(WORM) tape cartridges. WORM tape cartridges provide an enhanced level of data security
against alteration of data because you cannot erase or overwrite them. To check whether your
backup or archive software application supports WORM tape cartridges, see the following web site:
http://www.hp.com/go/connect .
For optimum performance, always use a tape cartridge that matches the specifications of your tape drive.
Table 3 on page 20 shows tape drive compatibility and tape capacity.

NOTE:
In addition to the information provided in this manual, see the documentation provided with your media
for more information.
CAUTION:
Ultrium tape drives require special cleaning cartridges and data cartridges formatted specifically for
HP Ultrium. To avoid damage to your tape drive, it is critical to use appropriate cleaning cartridges
and properly formatted data cartridges.
Approved media has the Ultrium format trademark, which indicates the media has passed Ultrium
format compliance testing.
For best results, always use HP branded media and bar code labels. See the HP StorageWorks Tape
Libraries Media and Bar Code Labels flyer for information on which media and bar code labels to
use in your tape drives.
CAUTION:
Do not bulk erase Ultrium formatted cartridges. This destroys prerecorded servo information and makes
the cartridge unusable.
Always visually inspect your tape cartridges when loading or removing them from your tape library.
Taking a few minutes to check the condition of your cartridges lowers the risk of repeated failures and
helps ensure uninterrupted backup.
CAUTION:
Always discard damaged tape cartridges. If a defective tape cartridge is loaded into a tape drive, it may
damage the drive, potentially requiring drive replacement.
