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.
