Description of Original Problem:

My 8tb WD White Label hard drive is occasionally not recognized upon booting the PC.

As in, sometimes I start the computer, and the drive shows up in windows explorer, and sometimes I start the computer and it's not there.

 

Troubleshooting:

I've tried changing sata power cable, sata data cable, and tested all 8 sata ports on my motherboard. The issue still exists.

I have 6 total sata devices plugged in, but the issue happens even when only the 8tb drive is plugged in, and the hard drive isn't the issue; This hard drive was used in my previous Intel build for over a year and never had an issue.

It's happened on multiple BIOS versions: P1.10, P2.10, P2.70, P2.80, P3.00

I've tried loading optimized defaults, to see if maybe it was an unstable ram overclock, but the issue still happens even with all stock settings applied.

Tried disabling esata support, still happens.

 

Tried reseating many things: CPU, RAM, sata power and sata data cables on both ends, GPU.

 

Anyone got any ideas?

When this happens is it showing in BIOS? How about Disk Manager?

If it's not in windows explorer, it's not in device manager or disk manager; but it is sometimes still recognized in BIOS, but not in windows; sometimes not at all (not in BIOS or windows).
