Yep, it's me again, Gared(icus) with yet another computer failure. Right now I'm working off of the permanent storage space on my Ubuntu install USB drive, because neither my desktop with the x370 Pro4 nor the new one with the X570 Pro4 will recognize my SSDs anymore. Not the 500GB one that my most recent Windows install is on, nor the brand new 2TB WD Blue SSD. No more SSDs - they've just vanished. It would be one thing if the MBR got eaten, but since Ubuntu can't find them on either motherboard I'm just completely and totally at my wits' fucking end. Anybody have any advice? They're both WD Blue NAND SSDs. It's either recover the 500GB drive, or start from scratch next Monday when my new low-end gaming machine gets here (because I had to have something).
