I attempted to do a clean install this morning. I was unsuccessful installing Windows 7 with the controller set to AHCI. My optical drive would not boot to the disc unless I set the controller to native IDE so I installed Windows 7 in IDE mode. I'll have to jump through some hoops later to switch to AHCI mode. I ran out of time this morning so I don't know if the S.M.A.R.T. error is still there.
The long boot time is still a problem even with the clean install. I timed it... 65 seconds just sitting there doing nothing, which makes my total boot time around 2 1/2 minutes.
Tomorrow, I'm going to attempt a number of things:
#1 Boot to a SATA addon card with the GA-MA785G-UD3H SATA controller disabled.
#2 Clone my fresh install to my 1TB WD black drive and see if its my hard drive that is causing the problems.
jnorris- What BIOS are you using? I'm using F4, and I think my problems started after updating the BIOS. I might try to roll back to F3 and see if that solves the S.M.A.R.T. error and long boot problems. Maybe the GA-MA785G-UD3H has problems? I can't find anyone else having these issues though. I'd hate to RMA this board, it has everything I need.
