Re: Tape error or device error?

It looks like DDS1 tape drive. Before doing tar please make sure that you've inserted DDS1 tape into the drive and it's not doing anything (not flashing its leds). Also please check with 'ioscan -fnCtape' that there's device file for this tape driver and you're using correct device file

Re: Tape error or device error?

No way. DDS2 tapes will not work within DDS1 drives. You need DDS1 tapes. Check with LTT http://h18006.www1.hp.com/products/storageworks/ltt/index.html
