Hi,

I'm running Windows 7 Professional on a Gigabyte GA58-UD5 motherboard with an Intel Core i7-940 CPU and Intel X58 chipset.

I have a Thermaltake external USB case that I had been running a 1 terabyte drive in for several years. Yesterday, I replaced the 1 terabyte drive with a 4 terabyte drive to better deal with my backup files. Windows Disk Management was able to see the drive and finally completed a full format (took more than 36 hours).

I formatted the drive as NTFS using GUID partition because that's what the Initialization Wizard recommended for drives larger than 2 terabyte.

Now that the format completed, Disk Management shows the drive as a healthy 3725.90 GB NTFS primary partition. Device manager sees the drive with no problems and shows it as Working Properly.

The problem is that My Computer doesn't see the drive, so I can't do anything with it. Am I missing something???

Steve

Did you assign a drive letter? But then again it's supposed to anyway...

LatiosXT,

That was it!!! It looked like the Installation Wizard was assigning the drive letter before the format started, but for some reason it didn't. I just assigned it to "F:" and now Computer sees it okay and I'm able to copy files to it.

Thanks,
Steve

Hmmmm. I'm just wondering if it will actually use all 4 TB. My guess is that it will only use 2 TB. The new Motherboards ( X68, X77, & X87 ), have a Disk unlocker that comes with the utilities & Drivers disk to unlock it to run more then 2 TB. At least ASUS does.

Well, Windows 7's file explorer shows the capacity as 3.63 TB formatted, Disk Managemet shows it as 3725.90 GB, and Device Manager shows it as 3815318 MB. So it looks like Windows sees the full capacity and it should fine. Guess I'll find out when I try to break the 2 TB barrier.

Steve

BTW
This isn't a boot drive. Just an external USB drive I'm using for backups. Maybe that makes the difference.

I believe the 2TB thing only applies to boot drives, and even then I think Windows 7 and 8 can boot from any GPT partition,

GPT boot support requires a EFI BIOS (edit: and 64-bit OS) which the Gigabyte GA58-UD5 does not appear to have.

From MS GPT Windows FAQ:
Q. Can Windows 7, Windows Vista, and Windows Server 2008 read, write, and boot from GPT disks?

A. Yes, all versions can use GPT partitioned disks for data. Booting is only supported for 64-bit editions on UEFI-based systems.
