I recently built a system using an ASUS M2NPV-VM mobo (AMD2) with a SATA Western Digital Caviar SE16 model with 320 GB. The bios recognizes the HD and shows 320GB as the size. When I loaded Windows XP (SP2), it only recognized the HD as approximately 127GB. This is the only amount I could format and partition until the system was completely set up. Afterwards I went into disk management where it showed 127 GB (Healthy) and approximately 180GB as unpartitioned space. I was able to partition this 180 GB space, format the space, and now use it for storage.

Any ideas relative to why the windows installation did not recognize the correct HD storage space?

Thanks.

It's something to do with XP only recognising up-to 127GB.

SP1 and/or SP2 fixes it.
