Pádraig.

"Though TBH I think what may be happening is that the lseek() does not rewind the tape at all and only resets the file offset."

Looking through the trace file I see only this line with 'lseek'.
lseek(4, 0, SEEK_SET)                   = 0

So I am guessing that what you suggest is correct?


"  shred -n1 /dev/st0 /dev/st0 /dev/st0"

Goodness, interesting stuff.
