Is there a doctor in the house? (data recovery help needed)

ok, so I turn off my computer and the next day I turn it on and while it's booting I get I/O error, please replace disk and hit any key. so i booted up using my windows cd

while attempting to save my disk, I ran a windows restore console which is sort of like a castrated version of dos, but anyway, the harddrive that crashed was divided into two partitions, only the first partition was unreadable, I tried running the repair master boot record, and now i can't read the second partition.

I switch the master and slave drives and finally get my computer to boot. and windows says that the harddrive has 0 bytes and is in RAW format, Maxtor's MaxBlast utility says that the harddrive is in FAT16 format, and only has 35GB available (It's an 80G drive)

What I think happened is somehow, the file allocation table was corrupted, resulting in the first problem of not being able to read the drive, then when I repaired the master boot record, the drive forgot it had a second partition. Now, I have a drive which thinks it's total space is only equal to the first partition, and the second partition is still there, but is hidden.

What I want, is to save the data from both partitions. I haven't formatted the drive, so the data should be recoverable. I was wondering if any of you guys knew of any good utilities or tricks that could help me in this quest.

PS I think the first partition was NTFS and the second partition FAT32... or maybe the other way around, not sure if that matters or not.

If you can change the size, and have a partition set aside (at the end of the drive), use gbr or whatever its name was (check the G&C history, I had a similer problem), it has high rates of recovery.

If you have a second [larger]hard drive, run an imaging utility to back the whole thing onto a second hard drive, then try parted from a KNOPPIX CD. "dd" might work, but is massively space intensive, Looks like your partition table is corrupted,

Anyway if it's a spontaneous error for no reason, it may be signs of a dying harddrive.
