Specs: Windows XP
I bought a new 1 TB hard drive. When I partition it I only get 130 GB. How do I get the full volume (1 TB)?

There are many reasons why you cannot get full capacity on the drive but without information on your system we could be here all day guessing as to which one it is.

The most likely is that you have come up against the 32 bit LBA limit. To use a hard disk over 137 Mbs you need both a BIOS and operating system that is 48 bit compliment.

Windows XP with SP1 or later will do it for the Operating System. What about the BIOS?

I have a new Asus M2N68-AM PLUS motherboard using XP with SP2. I bought it to overcome the 137 Mbs so I could make larger partitions but when I try it only allows me a maximum capacity of the HDD as 137 Mbs. My old Asus A7V600-X has two 250 Mbs HDD’s and only allows partitions 137 or smaller but at least it shows the 250 Mbs capacity of the drive’s. I built both computers.

You need to have at least SP1 on the installation CD in order to have WinXP recognize more than 137GB.

Your motherboard should tbe 48 bit LBA compliant. So unless you are using a third party controller card the only explanation is the installation CD.

You need to slipstream SP3 into your installation files and burn a new CD.
