Way Less HD capacity after WXP Clean install ???

I have a Sony Vaio laptop (400mhz, 256mb ram, 40GB HD) that had W2K on it. I wanted to erase everything and install WXP home. I booted in safe mode from the CD and deleted the C: & D: partitions and reformatted, and did a clean install of the OS.
Now the install went fine with the exception that the HD now states 9GB avail on a 11GB drive? Any ideas what happened with the rest of the 29GB?

Thanks!

 

If you restart and go into your BIOS, how large does it think the drive is?

 

Thanks Newt, I'll give it a try when I get home. Any chance it could be to damaged tracks?

 

Possible I suppose. I'm not that much of a hardware guy. I'd expect that a drive with that much missing from damage would be giving lots of other problems.

Also possible that the laptop had some sort of specialized drivers loaded as part of the original 2K install that set up the proper drive.

At this point I'm not really sure what is happening but if the BIOS has it mis-identified then any OS level tweaks would be a waste of time.
