Recovering partition table

I got these links from ilugc forum. These two links are for utilities which help in recovering the parition table of the hard disk which may have got damaged / destroyed for any god forsaken reason. I haven't personally tried this. Shall update once (if and no, i dont want such a situation) I try.

gpart - Guess PC-type hard disk partitions
testdisk - file as well as parition table recovery utility
