I have a curious failure that I have not been able to fix. I am running the DIY edition with a WD SN850X 2TB hard drive and Arch Linux. I was using the device as normal when it crashed, and upon restarting BIOS fails to recognize my SSD. I used my installation media to see if it was still connected, and fdisk recognizes that it is still in my system. Additionally, I was able to verify that its firmware was up to date.
Hi @jzmiller97 , Welcome to the community. 
can you share fdisk output?
also what firmware version are you at?
