This is good info for backing up the MBR (which includes the partition
table).

However, if you are going to image a partition use either ddrescue
(does the same thing but has a status screen, can resume, and works
around read errors) or partimage (has a status screen and it
understands (most) filesystems so it can leave the empty space sparse).
