But shred is supposed to rewind the tape, using lseek. Can you find out what system calls are executed? Use the command shred -o tracefile -v /dev/st0Warning: 'tracefile' will get quite large. The point is to see what happens near the start of execution, and around the time that the write files.
My guess is that 'shred' is incorrectly calculating the tape size; it does that by seeking to the end of the tape, and perhaps this is going awry.
