HDD spins but OS doesnt see mountable disk (infosec.pub)

The primary OS for this disk was Unraid. Its formated in BTRFS. I don't think either of those matter. The disk spins and worked before the reboot. But now. No matter what machine, port or cable I use its not mountable. Is there anything I can try? I was going to attempt Spinrite on it however it doesn't see anything either. Thanks! Its a HGST drive dated May2019

I think that mount the mount(1) command is probably calling the mount(2) system call, and it's returning ENOENT, error 2. The mount(2) man page says "ENOENT A pathname was empty or had a nonexistent component.".

Hmm. So, I expect from the cyan color there that that "luks-d8..." thing is a symlink that points at some device file that LUKS creates when that luksOpen command runs.

Maybe ls -l /dev/mapper/luks-d8... and see what it points at and whether that exists as a first step? It's probably gonna be some device file somewhere in /dev.
