Kevin,
Thanks for your attention to my problem.
By RAW I mean that in Windows Computer Management/Disk management, the file system shows as RAW, rather than NTFS. When this happens Windows considers the data unrecognizable. The only way I have found to get Windows to do anything with the drive is to format it.
GAZ7711H.86A.0066.EB
Drives have been working fine until now. Hibernation/Rapid Start etc has never worked correctly. I tried all kinds of things when I was building it to get the Rapid Start to work and wasn't successful. Unfortunately, by now I forget what all I had tried back then. Someone I chatted with at Intel back then had informed me I needed a separate drive for the hibernation partition
Board had BIOS GAZ7711H.86A.0066.2013.0521.1509, I re-flashed it with the same, and it starts faster than it did so it appears to me that something was messed up before. Unfortunately, the drive still went RAW since this, so I'm inclined to believe it had nothing to do with the drive problem.
Today the computer is going to sleep by itself, (and not doing the little restart for hibernation), but it still does do the restart when I shut it down. I'm afraid the not going to sleep yesterday is due to a program running (my VPN) which seems to prevent sleeping today also. Formerly, it did not. Again, this may be a different issue.
From communicating with Seagate, it does appear the disks are physically good. Again, I can't get them to show any physical problems with either Seagate's SeaTools, or Windows' ChkDsk.
