Resetting the Drive
You can reset the drive without powering off the drive and system. This may be necessary if the drive stops responding. To do this, press and hold the eject
button on the front panel of the tape drive for 10 seconds (Figure 13). The drive forces a dump of vital technical data to drive memory and overwrites the
existing dump. The drive then reboots to allow communication.

Loading, Unloading, and Write-Protecting Cartridges
Use only LTO Ultrium format cartridges with your drive, as specified in the LTO Ultrium standard. Ensure that only one label is stuck to the label area of the
cartridge. Do not use nonstandard labels, and do not stick anything to the cartridge other than in the label area.
