using dd to backup entire hard drive

[Craig White]

As a follow up, being the impatient person that I am, I just went ahead
and did it.

dd if=/dev/hda of=/dev/hdd bs=512

and it worked fine (target drive was slave on secondary controller,
hence /dev/hdd

copied everything but left the extra space on the target drive
unpartitioned and obviously parted would have to be used to move and/or
resize partitions.
