Hard drive shows as wrong size

Hi,

I know this is probably a common problem, but I've searched and I've searched and I can't find a solution, so I wondered if you guys could help.

What happened is, my PSU frazzled which in turn corrupted my main hard-drive. Now, I recently this hard-drive into a different computer, and have been able to recover around 20gig of the 160gigs of data using tools like GetDataBack. However, now I'd like to format it and start again, but the hard-drive only shows as being 31gigs as opposed to 150-160. Could anyone tell me how to rectify this problem? The really annoying thing is I think I had a similar problem with a previous hard-drive that I managed to solve in the end.

Here are the specs for this computer, in far more detail than entirely necessary. If anyone can help, it would be much appreciated! Cheers.

Get the manufactures tools & scan the drive to make sure the are no defects and it will prep the drive for install too.
The other way is to fdisk and delete all partitions then create one that is the size of the drive or what ever you want.

Good tool to have is the ultimate boot cd

Problem solved! Cheers!

I downloaded the boot CD, which is a very handy little thing to have, ta for that. However, it was some hard drive software on their which actually pointed out jumper settings and such to me. This refreshed my memory quite a bit, and it turns out I'd been mucking with the hard drive jumpers and accidentally limited the capacity of the hard-drive when I tried to turn it from master to slave. Ah well, fixed now. Thanks!
