OK, the problem we have is this. In my partner's new machine, we've got 2 harddrives, both Maxtor, one 250GB and one 200GB. The bios detects them at these sizes, but Windows doesn't. We've tried slipstreaming sp2 for the installation, but it still only shows 127GB of space for each one.

Any ideas?

bios update?
 
Some hard disks come with software (or have software available on manufactuers site) that will correct this issue.

Might be worth checking out.
 
Those hd's look big enough to be newer than jumper space limiting (but wth, maybe they do?). Check out XMS's suggestion, Winblows might require some uber-retarded driver to make them display the correct amount of space?
 
Seems like a registry problem as windows cannot identify the bigger drives. This should be fixed in Sp2 but it seems like your slipstream had no effect. The issue happens in windows 2000 and windows xp Sp1. There was a utility to download and enable large drive support in windows xp which changes registry to recognise bigger drives.]

Maxtor's Big Drive Enabler is a one step executable that enables support for drives larger than 137 Gigabytes in Windows 2000 Service Pack 3 and XP Service Pack 1. This utility takes the guess work out of editing the Windows registry. The Big Drive Enabler fixes an operating system limitation. This utility is needed anytime a Hard Disk Drive larger than 137 GB is connected to the motherboard's ATA bus, regardless of any system BIOS that supports 48-bit LBA.

If that doesnt fix your problem check this page out on Maxtor:

Question

I have a drive that is larger than 137 GB but the operating system only recognizes 128 GB or 137 GB. How can I fix this?

Answer:

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.

I looked at this and was gonna suggest that Tec but work and you beat me to it.

Give that a go Danni and see how it goes :)

Nice work again Tec - you are proving yourself as a very useful and knowledgable member :wavey:

No problem at all Kempez , i like to help.

Danni i believe this was a new system for your other half. if you cant sort the problem out perhaps formatting the drives with Maxtors MaxBlast tool might help. Latest version is v4 and can be downloaded from below url.

when u say windows doesnt find it....do u mea actual windwos install..or the setup process?

cos event he setup wont read correctly...u have to actually install.
 
Even the setup doesn't find it- when trying to do the partitions. He doesn't mind having another partition (or two) at the moment, as he doesn't want to reformat again, but if he gets another hard drive he wants to be able to use all the space :)
 
i meant....and said..the setup wont recognise the extra space...windwso setup can only see 127gb.

once u are in windwos u will need to format the "unpartitioned space" in disk manager
