Write Protecting Cartridges
Compatible media can be recognized by the Ultrium logo, which is the same as the
logo on the front of your drive. Do not use other format cartridges in your tape drive
and do not use LTO cartridges in other format tape drives.
For optimum performance always use a data cartridge that matches the specification of
your tape drive, (see table below). A lower specification will have a lower transfer
speed and may not support write activities; a higher specification will not support read
or write.
Write Protecting Cartridges
If you want to protect the data on a cartridge from being altered or overwritten, you can
write protect the cartridge.
!
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.

Note. This table shows the importance of a sequential progression for LTO drives. Customers
need time to upgrade their media, skipping a generation creates media management issues.
WARNING: Always remove the cartridge from the tape drive before you change the write
protection.
