I just put a 4TB Western Digital hard drive in my system (Win 7 64bit). It sees the drive at its full size in the bios and in disk management but I cannot get it to format to over 2TB. The other 1.7 or so shows up as unallocated no matter what I do.

Any suggestions?

Thank you

The drive has to be initialized by using the GUID partition table (GPT) partitioning scheme and not MBR, which is what I'm guessing you tried to set up the drive with?

Could be. Is there a way to switch it? I read online that there is an option when you select the drive to convert from MPB to GPT but that option does not appear in disk management.

Delete all the partitions/volumes on the disk until it shows up as "unallocated space" and then right click (disk 1 for example) and click on "convert to GPT disk"

Tried that, all I get is an option to create new simple volume. There is no option to convert.

It will not show up as a single volume even if I delete the partitions.

Can't think of why that would happen. Try using CMD to convert for you?

Open cmd and type diskpart and then enter. Type list disk and press enter again.
Select the disk you want to convert e.g, disk 1 by typing select disk 1.
Seeing as you don't have any volumes on the drive (deleted through Disk Management) just type convert gpt and then enter. This should do the trick for you

What's going on here? Just go to the link I posted, all the information is there.
