While conceptually is could be a cable problem. Check the cables are
not loose to the drive.
Every time I have seen this, the Device has been faulty, or about to
completely fail.
Backup all your data, if you need any of the data, because the drive
is about to fail for good.
After you have done the backup, you can try things like moving it to a
different known good cable, and known good connector on the board.

Note, if you reboot or power cycle, the drive might not appear again.
If you can, try to post the output of:
smartctl -a /dev/sdX  (where X is whatever the right your device)

It will probably hint at other things wrong with the drive.

Kind Regards
