[aklug] Re: Using DD to find partition table

I really like Leif's idea. The other option that occured to me was rather
than using dd with the offset, you could use a loop device, setting the
offset.

Assuming that you don't have any loop devices in use, your loop then
becomes:
 i=1; while true; do losetup -d /dev/loop0; losetup -o $i --sizelimit 512
/dev/loop0 fake-sdb; echo $i; file -s /dev/loop0; i=$((i+1)); done 2>&1 |
grep -B1 /dev/loop0 | grep -i -B1 'boot sector'

you can then use losetup on your actual drive to access a single partition,
if you want:
losetup -o $offset --sizelimit $partionsize /dev/loop0 /dev/sdb
