Any way to rescue corrupted partition table on hard disk?

I have a 20G hard disk that is (used to be) divided into 5 partitions.
When my computer booted up yesterday, only the C partition was visible -
the other partitions, containing all my personal files, installed games and
digital photos, had disappeared without a trace. Partition magic, which I had
used to partition the disk in the first place, informs me that "Logical drive
chain points to sector without partition table." Is there some utility that
can recover my partition table for me?

 

Disk Doctor, which is part of the Norton Utilities or Norton System Works depending on your OS, may be able to correct your problem.
