I am almost to the end of figuring out this problem.
First, I had my desktop running a raid setup, and had several issues with my 3tb HDD not showing above 746gb. I then used GParted to partition it as one large drive. That worked for a while until my computer just quit working right, and had several drive read errors on the first 3tb drive.
So I sent it off for a replacement, but I decided to do away with the raid setup because after extensive research, I found that when I enable raid, all sata ports run on raid, and the chipset I have was having compatibility issues with large drives and raid. Instead, I just implement regular drive backups.
The odd thing is that the BIOS recognizes the drive as 2.72TB just fine, but when in windows with a super fresh install, and all the updates installed, it still only sees 746gb even after initializing the disk.
Any suggestions on how I can get windows to see the full capacity of this drive.
My BIOS is updated, and as the drive displays correctly during POST, I still strongly feel this is a windows issue.
The motherboard I am using is an ASUS M4N78-Pro.
