Hi,

Are the tape new?

Did you try different tape?

Did you try to write to the tape "by hand": tar cf /dev/st0 ...

I see that your SCSI card is Ultra 160 but your tape drive is only
fast wide, do you have any disk pluged in that SCSI interface? It
should work, but who knows, if you can (have 2 SCSI interface)
separate fast disks, from slow tape.

Best regards,

Olivier
