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 amber 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 23 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.
