Look at the 'skip' option in 'man dd'. That should do what you desire.
Loop it 100 times, with a bash script something like:
while [ $count -le 100 ]; do
dd if=/dev/fd0 of=/dev/null count=1 skip=1
dd if=/dev/fd0 of=/dev/null count=1 skip=2940
That should seek from the 2nd block to nearly the last block of a 1.44MB
floppy drive ~100 times. I didn't test this but it should work. Might
need minor modification.
