I installed a 3TB Seagate drive into my PC about a week ago. The BIOS detected it as 3TB. Windows 7 64bit formatted it fine. I moved all my documents, photos, etc. to this new drive. Once I ensured that it was all working, I formatted the old drives, etc. A few days later the 3TB drive appears as RAW. CRAP!
I'm trying to recover what I can using TestDisk v6.14-WIP. For some reason TestDisk reports that this drive is only 801GB.

Is there a reason for this? Do I have any hope of recovering what is on this drive?
Thanks!
