Here is the bottom line as of 6/3/16: I updated the BIOS and thought that fixed the problem but it did not and dropped the HDD drive again. After reading up on the manual a little more realized that when using a M2 it takes up 4 PCI lanes - which is 4 of my SATA connection ports. I could only use 3,4 10 GB second and 6,7 for powering devices and I think slower 6 GB second traffic (I still am not 100% sure of the difference) anyway....I switched a disc drive and my HDD SATA around and now my HDD has not disconnected in days but my disc drive does not work. So long story short I believe my #7 SATA port is bad. I don't know how common it is for a single port to go bad, but that is what I have narrowed it down to. This Gigabyte board is less than 1 year old and overall I really am not happy with the board or their software, I wish I would have gotten an ASUS Maximus Board like my last one.
Within about an hour or so after computer is turned on, I will hear a ding and I go check my PC file and one of my drives is missing, first it was my Samsung SSD now it tends to be my HDD. If I restart the computer the drive comes back. I tried changing the cables around and checking power connections but did not fix. My next step is to do a motherboard bios and Sata driver update. Could these updates be the culprit?
