New System not recognizing all 320 GB on HD

[Captk]

I just built anew system and tried to load xp sp2 this morning. The system is Gigabyte MA790X-UD4P motherboard, AMD Phenom 720 X3 processor, 4 GB GSkill 1066 memory, Sapphire 4830 video card and WD 320GB hard drive. I am using windows xp sp2 system disk. When it comes time to format the drive, it is only recognizing 131GB, not the full 320 GB. Do I need to load XP with SP3? Any suggestions?
Thanks, Ken

i was going to say some loss is normal due to the files system, how manufacturers rate 1gb vs how ms does, but that is way to damn to low. Did you partition the drive weird or something? I got a drive that is defective and refuses to think it is a 80gb drive, it stuck at 30gb some how.

I tried loading windows again and it now is recognizing the hard drive's full size. Strange.................
Thanks, Ken

I think around 137GB is the maximum without the Physical Address Extension. I believe it is included in SP1 though, so it's possible that the extension didn't install properly the first time. Anyways, you have it fixed now.
