Well, the plastic wrapping on this DDS-1 tape tells me of 3 versions of the
DDS-1 tapes, 60, 90 and 120m, equals 1, 2 and 4 GB respectivly.

I could run the tapetype again if you want. I did once, but maybe I got some
strange results, see below for my previous mail to the list about the
tapetype.. well.. since I'm going to work now, I just started the tapetype
util again, this time with /dev/nst0 instead of /dev/st0:

./tapetype -e 2g -t "HP 90 meter DDS-1 Data Cartridge" -f /dev

Probably have a result when I get home.
