Odroid HC2 missing disk :-( Failed?

Went to access some files tonight, only to discover the share was not functioning. The device had been functioning with no problems for the last 10 months with no recent configuration changes.

I'm using an Odroid HC2 with 10TB disk.
Storage -> Files System reports the drive status as missing.

Running OMV 4.1.12.

cat /etc/fstab produces

sudo fdisk -l does not list the 10TB drive

Output of armbianmonitor -u here following a reboot.

I've read in this thread that a reinstall might solve the issue if it is connected with hdparm.

Multiple reboots have had no effect.

Using the original power supply that came with the HC2.

Anyone have suggestions as to what I can do?

TIA!

Well I pulled the drive out and attached it to my UAS USB controller.
It is bad news.

Linux laptop wouldn't see the drive at all.
Windows 10 beeped to acknowledge the drive adapter, then beeped as if it had been unplugged. It kept this mount / unmount loop going, although at no time did the disk appear.

Looks like my HGST is going to have to go back for a warranty replacement

Thanks for the help all the same Adoby. Was glad to see you chiming in!
