Write-protecting cartridges
If you want to protect the data on a cartridge from being altered or overwritten, you can write-
protect the cartridge.
Always remove the cartridge from the tape drive before you change the write protection.
• To write-protect a cartridge, slide the red tab by the label area on the rear face of the
cartridge to close the hole. Note the padlock on the tab that indicates that the cartridge is
protected.
• To write-enable a cartridge, slide the red tab back so that the hole is open before loading
it into the drive. Figure 11 illustrates the location of the write-protect tab.
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.
Cleaning cartridges
You must use Ultrium cleaning cartridges with HP StorageWorks Ultrium tape drives, as other
cleaning cartridges will not load and run. We recommend the HP Ultrium universal cleaning
cartridge (see table 3). Unlike some earlier Generation 1 Ultrium cleaning cartridges, the
orange-colored Ultrium universal cleaning cartridge is designed to work with any Ultrium-
compliant drive. Do not use other format cartridges in your tape drive and do not use Ultrium
cartridges in other format tape drives.

To clean the tape drive
HP StorageWorks Ultrium tape drives do not require regular cleaning. An Ultrium universal
cleaning cartridge is supplied with each tape drive and should only be used when the orange
Clean (Ultrium 960 and 460) or Use Cleaning Cartridge (Ultrium 230) 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 (Ultrium 960 and 460) or Use
Cleaning Cartridge (Ultrium 230) LED will be on solidly and the green Ready LED will flash.
Each HP Ultrium universal cleaning cartridge cleaning cartridge can be used up to 50 times
with Ultrium 960 and Ultrium 460 tape drives, and up to 15 times with Ultrium 230 tape
drives. (HP Ultrium 1 cleaning cartridges can only be used up to 15 times with any tape
drive.) If the cleaning cartridge is ejected immediately with the Tape Error LED on, it has
expired.
Caring for cartridges
It is important that you look after your HP media and adhere to the recommended guidelines.
