Hard Drive (40GB) shows only 8GB

Issue: My 40GB Maxtor hard drive only shows 8GB in my computer C Drive properties. I'm moving this Disk to a "newer" PIII computer.

Request: I'm looking for direction to make it see it all. Note I am aware of some issues with BIOS's not recognizing the disk, although I don't know how to go about correcting this issue.
Any help direction appreciated.

Details:
Singel Partition - contains WinSE, MSOffice, loads of software.
BIOS was originally set to auto have since changed it to "User"
