The simplest way to copy a healthy disk is dd:

   dd if=/path/to/source of=/path/to/dest bs=512

You can then mount the file and it will look like a filesystem.

"man dd" will provide more info about options, including how to ignore
errors, use different block sizes etc.

Be extraordinarily careful using dd; if you muddle source and
destination you can obliterate your own disks and partitions.

photorec is pretty good at recovering files automagically.
