Hey there,

I just received my new 4TB HDD (Western Digital Black WD-4001FAEX). When I try to partition it with the Windows hard drive manager it only shows me an available size of 2794,42 GB, so only around 3TB. I initialized it with GDP.

How can I get the whole 4TB?

My System configuration:

Windows 7 64 Bit
Gigabyte Mainboard: GA-MA69G-S3H
AMD Athlon X2 Dual Core BE-2400

... did i miss anything?

The first thing I'd do is make sure your BIOS is up to date. It's an older board so you might have to go with an add-in SATA card if the onboard controller just won't let you use > 3TB.

:D Wonderful, it works. Just worked myself through the BIOS update and now after rebooting Windows shows 3725,90 GB capacity on the new HDD. That should be the maximum possible size for that HDD, right?

Perfect, thank you so much!

Gigabyte's Xpress Recovery BIOS has a bug that reduces the capacity of your drive by 1TB (not 1TiB).

See Q2:
http://www.users.on....pacity_FAQ.html

It appears that 4TB drives are reduced to 3TB (not 3TiB).
