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
Its telling you the Mount point doesn’t exist. Create the dir at whatever that /media/pkms/paththatsreallylobg
Whats the contents of /etc/fstab
