P4P800-E Deluxe - wrong drive size

November 12, 2007 at 16:39:12
Specs: W2K Pro, 3.6 P4 - 2 gigs DDR400
Been all over the Asus site, ran a bunch of Google searches and... well... here I am.
I just added a Seagate 750 gig SATA drive to my setup using the connection right on the motherboard, an Asus P4P800-E Deluxe. It's not connected through a controller card or in an external enclosure. Went to computer management to format the drive (NTFS) and all I get is a 128 gigs. Definitely don't understand the limitation because there's a 160 gig SATA on the same controller on the board and it reads as it should.

Any thoughts here? Details upon request.

Okay - an update of my own - The 160 isn't being reported correctly either. It shows the same size as the 750 and they're not 128 - they're showing as 127. LBA is enabled in the BIOS.

You evidently are using Original WinXP. You must have at least SP1 or better in order to support 48bit LBA.

Your version of XP support 28bit LBA.

Slipstreaming the latest SP into your install CD will solve this problem along with providing support for USB 2.0.

I wouldn't say it's obvious - I'm running Windows 2000

A round of drinks for the house... I got this one myself. Didn't know there was 28-bit and 48-bit LBA.

Found this page which shows how to enable 48-bit LBA.

Got my gigs!

OK sorry about that. That's what I get for covering 4 forums.

Hope you are using at least SP3. Enabling LBA with an earlier version can cause problems.
