I'll apologize in advance if this topic has been beaten to death... Searching was unsuccessful for my individual problem.

I purchased the WD Caviar Green 3TB SATA 6gb/s WD30EZRX. I know its not the best of the "big three" but I plan to use it only for mass storage. After physical installation Windows does not detect the hardware change at all. However, the drive is detected in my BIOS.

I understand that most motherboards max out at 2TB so they the 3TB drive is supposed to be automatically partitioned into one 2TB and one 800GB. I used Partition Wizard and for whatever reason it only found one unallocated drive of 746gb(aprox) and not the second 2TB... The program also never gave me the option to "format" just "wipe". I didn't do anything yet as I don't have experience with this.

I also heard there are PCI-E hardware cards that can be installed as a simple fix. I don't want to do this if I don't have to and I also heard that this was only necessary if you wanted to set up a 3TB as a boot disc. I am only planning to use this drive as plug and play storage drive. I assume that if BIOS can identify the drive there should be away to reconfigure my system to identify the full 3TB drive as a storage unit...

I'm trying this with the following:

Mainboard: Gigabyte H55M-UD2H
Hard drive (in question): WD Caviar Green 3TB SATA 6gb/s WD30EZRX
OS: Windows 7 Home Premium 64bit
CPU: Intel i5 quad core 760

If anyone could provide me a guide or some form of instruction in how to reconfigure my system to get this to work. I would greatly appreciate it!

Thanks in advance.

If the drive is recognized in BIOS, but not windows, it may just need to be initialized and formatted.

  • Right click on "My Computer," either on your desktop or your "start menu."
  • Select "Manage," then "Disk Management."
  • Find your new drive and right mouse click on the "Disk_X" label (see below).

  • Select "Initialize Disk" and then format.

I would simply create at least two partitions, deleting the current structure on the 3TB drive...and creating no partition larger than 2TB.


I see no advantage in having a single partition of approx 3TB, nor does Windows XP :). The problem stems from the fact that Windows is designed for MBR partition system, while drives larger than 2TB use




I could be misunderstanding how this works, as I have no drives or partitions larger than 1.5TB.

As you can see a problem for many.


Take note of the fact that I'm not brave enough to install a 3Tb drive in my computers. I do have 3TB USB drives that work.

I found the solution elsewhere on the fourm. It is listed below. It was a bit scary installing an update to my chipset but it worked perfectly. My 3TB disc is now showing capacity at 2.72TB. Much better that the 746GB before the fix.
Re: Windows 7 64-bit won't show full size 3TB of WD30EZRX
If you have Intel chipset you have to download latest version of chipset.
My chipset is Intel Q57
In my case helped newest chipset version


Make sure you get the proper driver that matched your chipset.

Good Luck
