have you tried connecting the damaged disk as a second HDD on an operational XP machine (or just boot with a live cd like WinPE/BartPE/Winternals/Knoppix/Ubuntu/etc)? if it can boot and see your partitions on the damaged drive, you can try to use R-Studio to recover whatever is recoverable.
Another question - does the drive make clicking noises? If it does it really should go to either trashcan or a special (and very expensive) lab.
