USB drive won't auto-assign letter - can't deactivate partition attribute hidden

When I plug in a particular USB hard drive it doesn't get a drive letter assigned automatically. I've tried it on a couple of Windows 10 computers - same deal.

There is only one partition on the drive, and I have discovered that the partition attribute 'hidden' is active on it, but when I try to deactivate it (using 'attributes volume clear hidden') it just says there's been an error, and the system log shows this:
'Unexpected failure. Error code: 1@01010015'.

Someone help, please, before I throw the whole lot at a wall. Hard. Thanks.

Code:

Disk 0 / Status: Online / Size: 931 GB / Free: 0B / Dyn: / Gpt: *

0 bytes? That doesn't sound very believable...
