8 Use the correct media For best performance we recommend HP branded media. Order online at: http://www.hp.com/go/ storagemedia. If you do not have internet access, refer to the User's Guide on the HP StorageWorks Tape CD-ROM for ordering information for tape cartridges and cleaning cartridges. Data cartridges HP StorageWorks DAT 160 tape drives and HP DAT 160 cartridges HP DAT 160 cartridges (C8011A) can only be used with HP StorageWorks DAT 160 tape drives; they are wider than earlier formats and will not fit into earlier tape drive models. DAT 160 cartridges provide optimum performance and maximum capacity for HP StorageWorks DAT 160 tape drives. DAT 160 tape drives are also backwards compatible with some earlier formats, see Table 5 on page 47. Compatibility For optimum performance and storage capacity, use tape cartridges that match your drive's format, and normally use only one cartridge per day. Ideally, use: • HP's DAT 160 cartridges with DAT 160 tape drives • HP's DAT 72 cartridges with DAT 72 tape drives • HP's DDS-4 cartridges with DAT 40 tape drives Although HP StorageWorks DAT tape drives are fully backward compatible, old tape formats are more abrasive than later generations and using older tape formats can reduce the life expectancy of the tape drive. The compatibility between drive models and cartridges is summarized in Table 5 on page 47. Shaded boxes show the recommended media for each tape drive. Capacities assume a compression ration of 2:1.

Data cartridges
HP StorageWorks DAT 160 tape drives and HP DAT 160 cartridges
HP DAT 160 cartridges (C8011A) can only be used with HP StorageWorks DAT 160 tape drives; they
are wider than earlier formats and will not
fi
t into earlier tape drive models. DAT 160 cartridges provide
optimum performance and maximum capacity for HP StorageWorks DAT 160 tape drives. DAT 160 tape
drives are also backwards compatible with some earlier formats, see
Table 5
on page 47.
Compatibility
For optimum performance and storage capacity, use tape cartridges that match your drive’s format, and
normally use only one cartridge per day. Ideally, use:
•
HP’s DAT 160 cartridges with DAT 160 tape drives
•
HP’s DAT 72 cartridges with DAT 72 tape drives
•
HP’s DDS-4 cartridges with DAT 40 tape drives
Although HP StorageWorks DAT tape drives are fully backward compatible, old tape formats are more
abrasive than later generations and using older tape formats can reduce the life expectancy of the tape
drive. The compatibility between drive models and cartridges is summarized in
Table 5
on page 47.
Shaded boxes show the recommended media for each tape drive. Capacities assume a compression
ration of 2:1.
