Maybe your gfx card/main board combination doesn't leave enough room

Be sure to use the _latest_ version, i.e. ftape-4.04a. Otherwise you
will have problems to mix your windows backups with Linux backups on
the same tape, at least when using cartridges with more then (roughly)
2gig capacity.
OTHERWISE YOU WILL NOT ONLY RISK DATA LOSS, but you get data-loss.

The MTSEEK tape operation does not skip file-marks, but blocks. Use
ftmt -f /dev/nqft0 asf 2
(this is equivalent to doing a rewind first, and then an "fsf 2")
ftmt -f /dev/nqft0 seek 2
will just skip the first two blocks (probably 2kb when the first
volume has been created under Windows).
Be sure to do a "ftmt -f /dev/qft0 rewind" after the backup so that
the header segments are updated. Or use directly the rewinding device
with tar, i.e. "tar cf /dev/qft0 /home/whatever.
ALSO: do not use the "-z" switch with tar. If a single bit of your
data gets corrupted you'll have a hard time to recover the data from
your tape.
