2TB HDD showing up in Disk Management as 931.51GB

[adhesivehero]

Hey! Title says the gist of it, just got my computer running today and it's only showing my drive from an old PC correctly, and that's almost full. I installed another hard drive, a 2TB one, and it shows up in the BIOS fine. Under Disk Management though, it only appears to be at 931.51GB. I'm using a Asus - Prime X470-Pro Motherboard. Really looking to test this thing out, thanks.

Can you show us screen shot of disk management ? What does it look like in Device manager ?

Is there any option to extend volume in disk management, or unallocated space? If you were in diskmgmt youve more than likely checked already so I apologize, but I have to ask, ya never know.

This bug appears to affect some Asus boards, too.

GigaByte BIOS bug results in loss of 1TB capacity:

That's very small amount, certainly not by almost 1TB:

I don't understand what you mean ???

A 1TB drive is reduced to 32MB, a 2TB drive becomes 1TB, 3TB becomes 2TB, etc.
