I've heard windows can't see some of the larger drives (I have a
200GB and it's only seeing 127GB) but I thought installing the first
service patch fixes that (I have both of the service patches
installed) and it's still showing 127GB, anyone know how I can make
windows see the whole thing?

Start by updating your BIOS.

My BIOS sees the harddrive perfectly, it lists it as a 203GB

My motherboard is the Asus A7N8X Deluxe.
 
Hi,

Start/run diskmgmt.msc, does the snap-in see the full size of the drive?

If it does, then you need to use it to partition and format the free space.
You would need a third party tool to expand the existing 127GB partition to
encompass the free space.

IT seems that as has been stated upgrading your BIOS may solve the problem
if not you can patch windows to have it work

137 GB Limitation
Most system BIOSes are limited to 137 GB because it can only support 28 bit
Logical Block Addressing (LBA).

Problem
The full capacity of ATA drives larger than 137GB is not recognized by the
operating system.

Solution
Currently, there are three options to remedy the 137 Gigabyte barrier.
Failure to implement one of the following installation options will result
in data loss when trying to access the hard disk beyond 137 Gigabytes.

Installation Option 1. Upgrade the operating system to either Windows 2000
with Service Pack 3 (or newer) or Windows XP with Service Pack 1 (or newer)
and download the Maxtor Big Drive Enabler software patch. The Maxtor Big
Drive Enabler, once executed, will update the Windows registry for large
drive support.

Installation Option 2. Download and install the Intel Application
accelerator. The Intel Application Accelerator provides 48-Bit LBA compliant
ATA/ATAPI controller drivers (IntelATA.mpd) and replaces the Windows 98/Me,
2000 and XP ATA controller drivers (ESDI_506.PDR). Intel is the only chipset
manufacturer that we are aware of that offers a compatible controller driver
for Windows .

The Intel Application Accelerator only supports the following chipsets: 810,
810E, 810E2, 810L, 815, 815EP, 815G, 815EG, 815P, 820, 820E, 840, 845, 845E,
845G, 845GE, 845GL, 845GV, 845PE, 850, 850E, 860. The Intel Application
Accelerator can be obtained at http://www.intel.com/support/chipsets/iaa/.
If you have an unsupported chipset or do not want to upgrade the operating
system then try the next solution.

Installation Option 3: Attach the large hard drive to an add-in Ultra ATA
PCI adapter card with a 48-Bit LBA compliant BIOS and controller driver. The
adapter card bypasses the system BIOS and operating system's controller
driver and uses its own BIOS and controller driver.

Using an IDE ATA/ATAPI controller that has a 48-Bit LBA compatible
controller driver will allow safe use of large drives beyond the previous
limits of 137 GB capacity. Additional controllers that do not have 48-Bit
compliant drivers cannot safely access drives larger than 137 GB. A
compatible card such as the Maxtor Ultra ATA/133 PCI for Windows and Sonnet
Tempo ATA/133 PCI Card for MACs can be purchased at http://www.maxstore.com
(U.S. only) or at a local retailer.
 
Yes, it does, it shows 61.93GB unallocated, can I use the disk management to
format it with out extra software and just see it as like an extra drive?
 
Ignore the last message, I got it working.
