Cleaning The Tape Drive; Write Protecting Cartridges - HP EH920A - StorageWorks Ultrium 1760 Tape Drive User Manual

For detailed instructions about enabling encryption please refer to the documentation supplied with
your backup application. This will also highlight any default states, for example when copying tapes,
that may need changing if using encrypted tapes.

Cleaning the tape drive

HP StorageWorks Tape Blade tape drives do not require regular cleaning. An Ultrium universal cleaning
cartridge should only be used when the orange Clean LED is flashing.
1. Insert the Ultrium universal cleaning cartridge.
2. The drive will carry out its cleaning cycle and eject the cartridge on completion (which can take up
to 5 minutes). During the cleaning cycle the orange Clean LED will be on solidly and the green
Ready LED will flash.
Each HP Ultrium universal cleaning cartridge (C7978A) can be used up to 50 times with Ultrium tape
drives. (The blue HP Ultrium cleaning cartridges, C7979A, can only be used up to 15 times with any
tape drive.) If the cleaning cartridge is ejected immediately with the Tape LED on, it has expired.

Write protecting cartridges

If you want to protect the data on a cartridge from being altered or overwritten, you can write protect the
cartridge.
IMPORTANT:
Always remove the cartridge from the tape drive before you change the write protection.
• To write protect a cartridge, push the switch to the right to prevent any data recording on the
cartridge. Note the padlock on the tab that indicates that the cartridge is protected.
• To write enable a cartridge, push the switch to the left to allow data recording on the cartridge.
Figure 21 illustrates the location of the write-protect tab.
NOTE:
Write-protection will not protect your cartridges against magnets. Write-protection will not prevent a
cartridge being erased by bulk-erasure or degaussing. Do not bulk erase Ultrium format cartridges. This
will destroy pre-recorded servo information and make the cartridge unusable.
