Hello, sorry that it has taken me a while to respond, I have been trying some things out and seeing if they work over a period of time.
So far I have updated the BIOS, changed the SATA connectors (but not the power connectors), and updated/installed some drivers from ASUS. Doing all of these has helped but not totally fixed the problem. Now, if I cleanly shut down the computer I can later reboot and it works fine. But if I ever have to force shut down it sometimes won't work. In addition, it still fails to work when awakening from sleep mode so for now I had to disable sleep mode.
So should I still try to RMA the drive or is there anything else I could do to completely fix the problem?
