I have bumped into a simular problem with my HP 4GB DAT drive. It would
just refuse to write to some old tapes even after I ran these tapes though
a bulk erasure. I could not find a rhyme or reason for this. My solution
was to write a few end-of-tape marks at the beginning of the tape. Like so:
mt -f /dev/rst0 weof 5
I do not totally understand why this should work but a little cargo cult
never hurt anyone ;-)
