The trouble with hdd recognition

[MoD TaRkIn]

I've just put together a new system (been saving up for months to get it) and have run into a problem. Windows wont recognise all my HDD space, less than half infact (127GB out of 300GB). Re-running windows set-up makes no difference, it still only detects 127GB of the drive. This suggests it's a BIOS problem, yet according to the BIOS, the drive is 300GB in size! I'm updating the BIOS to the latest version now, assuming asus update connects to the server any time soon... But I'm not confident it'll make a difference. Any ideas people??? Heres the specs:

asus p5ad2 premium
p4 560J 3.6GHz
2x512MB corsair xms2-5400
radeon x800 xt
maxtor plus 10 diamondmax 300GB (or its suppost to be!!!)
NEC 3520A dvd-rw
samsung dvd-rom with a stupidly long model number
creative audigy2 zs
dell 2001fp
lian-li v1000

EDIT: Oh, it's a SATA drive btw...

Assuming your using WinXP, then you need SP1 or SP2.

omg, duh me. It never even occured to me that I was using an old copy of windows...I thought i'd picked up a sp2 one, but I actually put in an original copy of xp.. i'm off to update then, thanks.

i had the same problem, before, too. I just resized the drive and installed SP2. Of course, a few days later, my drive stopped showing up in the bios, so i don't know what the hell the problem is.

Well, I got it working. Still can't beleive I was that stupid...
