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 attempted to mount the disk and it says “unable to mount”.

    I think there might need to be more than one cylinder. (Referring to photo) Hmm…

      This is the error from my laptop when I try and mount. It asked for the encryption password just before this. And makes all the normal annoying hard drive sounds.

          Okay, it looks like you posted this prior to me posting my comment above. I’m not familiar with this graphical utility, but I’m assuming that it means that your disk is visible (like, if you run ls /dev/sda, you see your disk).

          So what you’ve probably got is a functioning hard drive, with a functioning partition table, and on the first partition (/dev/sda1), a LUKS layer.

          I haven’t used LUKS, but it’s a block-level encryption layer for Linux. It’ll have some command to expose an unencrypted layer, and you can mount that.

          Let’s try walking through this in a terminal.

          From https://superuser.com/questions/1702871/how-to-do-cryptsetup-luksopen-and-mount-in-a-single-command, it looks like the way this works is that one runs:

          $ sudo cryptsetup luksOpen <encrypted-device-name> <unencrypted-block-device-name>

          Your encrypted partition name is presently at /dev/sda1. So try running:

          $ sudo cryptsetup luksOpen /dev/sda1 my-unencrypted

          That should prompt you for a password. If it can decrypt it, it looks like it creates a block device at /dev/mapper/my-unencrypted.

          You can then create a directory to use as a mountpoint:

           $ sudo mkdir -p /mnt/my-mount-point

          And try mounting it (assuming that it’s just a filesystem):

          $ sudo mount /dev/mapper/my-unencrypted /mnt/my-mount-point

              considers

              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.
