Partition recovery

[Ziprar]

Would anyone know of a good partition recovery tool?  I've had a few machines come in where everything on them is fine EXCEPT the partition table.  Lovely.  If I could find a way to repair the partitions, I could just get 'em fixed up until the person realizes they probably either A) Need a new hard drive or B) Shouldn't be SCREWING AROUND WITH SOFTWARE THEY DON'T KNOW.  Ahem.

Any advice would be much appreciated.

I've had some success with PartitionDoctor (http://www.ptdd.com/) - good luck, I know these situations can be a pain.
