Thanks to all for your input!
I need to get another drive so I can ddresuce this drive. Actually, I will
probably just replace the whole machine with something better.....time to
upgrade from a 486 to a i7 or some such beast. Also, I was thinking of
using dd_rescue so I could copy the drive to another machine across the
network as opposed to installing a new drive in the current machine. Any
issues with that?
BTW, I was able to recover all of my mysql tables using knoppix. They are
now fat and happy in their temporary home on a new shiny linode....;)
