Hi Jeffrey

It seems to me that you are not using a driver, which makes me wonder how you got

your stuff on the tape in the first place. Anyway, I think you need something
like "mt" of "ftmt" to position your tape at the head of the file you want to
extract with a command like "ftmt -f /dev/nqft0 fsf n", were "n" is the number of

the file, probably starting to count from zero. See the man page for "mt". Hope
this helps. Cor.
