Simple question -- are they 120m tapes? There are no DDS-II tapes that
are not 120m, and there are no 120m tapes that are not DDS-II.
Another test is to run a backup, turning off software and hardware
compression with "mt -f /dev/st0 datcompression off". Your throughput
to the drive should be ~366K/sec with DDS-II. With DDS1 you will get
~175K/sec.
I hope this helps.
