I have this PC:
P67 Pro3 / BIOS version 3.30 / Intel Core i7 2600 3.40Ghz / 16Gb DDR3 / SSD 240 Gb with Windows 7 Ultimate instaled on it / HDD WD Black 4TB, 7200rpm, 64MB, SATA 3.
Problem: Into the bios/uefi settings, I can see the 4TB HDD as listed but with 0 [zero] capacity , Not even 2TB disk.
I can not access this hard disk, not showing into Computer Management > Disk Management , I can not use it. It's new, just reinstalled the W7 and hoped this will solve the issue, but still I can't access this new HDD.
I know is over 2TB but my Mount Board is up to date for it.
Any suggestions will be a HUGE HELP!!!!! PLEASE!
I installed 3TB+ Unlocker from ASRock as they suggested but nothing happened

The 4TB HDD is not listed on Disk Management. The only part were I can see it to convince myself it's actually working, it's on BIOS Hard Disks list. There is listed, shows that I have connected it on SATA 3, but with zero space capacity and with the notice "S.M.A.R.T.: Not Supported"
When the PC starts, the 4TB HDD is working, has even more noise than the other drives, but the sound of the 4TB HDD stops right before the windows finishes the loading...
Thank You!

Taken from the web, would suggested something similar but CBA on the phone :p

" It seems your SATA port is 32bit LBA, therefore it can only see 2TB.

You need a add-in card that has 48bit LBA to see the whole 4TB.

2nd though. Check your BIOS, make sure you have the latest BIOS. It may fix the issue."

to make use of all capacity of hard drive which is larger than 2TB, you need to use GUID partition table instead of MBR. otherwise you can only use 2TB capacity of the 4TB hard drive.

It's not going to be easy to explain the differences between GPT & MBR in a short forum post so here's a link.

2.5 years on I think the OP isn't still waiting for an answer...
