I've read of some large HDDs having such issues if they use the new, more storage efficient sector sizes. If you have a way of backing up what's on the 2 TB drive then I'd do so and then zero fill it if possible using a WD HDD utility (most drive manufacturers put utility software on their websites for such purposes). I'd also make sure the motherboard BIOS was up to date but note that some 55 series boards have had issues documented in these forums with BIOS updates causing compatibility problems with graphics cards - the latest BIOS rev for this board (and the one before) both updates claim to have addressed these graphics card related issues but I'd definately make sure anything of value was backed up before attempting to flash the newest BIOS.
The other thing which may cause what you're experiencing is if the 2 TB drive is being detected as the boot drive but isn't bootable. Is the 2 TB drive correctly detected in the BIOS now?
F_K had the answer to the puzzle. I was about ready to zero out the drive because I formatted it on my
vista laptop thinking that may have been the snafu. I thought I'd look at the BIOS before I went through the zero out and format which really didn't seem like the solution. Sure enough, the BIOS was flipping the boot disk off the number one position. This never ocurred to me because it sounded dumb. Maybe we are still a few years away before truly smart computers are made. Now, if Ican ever get my IDCC to work everything will be perfect.
