Corrupt External Hard Drive

I've got a 2TB Toshiba external hard drive. The computer I have it attached to is running Windows 10 Pro (64 bit).

When I plug the external hard drive in via USB 3.0 to my computer I can see the drive's partitions in Disk Manager, but my PC will not give it a drive letter. Even if I right click on the partition "Mark Partition as Active" is all grayed out.

I have tried plugging this external HD into both Windows and Linux machines with the results being the same.

Without the drive getting a letter I can't do much?

What to do next?
 
Can you physically take the drive out of the enclosure and try hooking it up directly to the computer? Have you tried running diagnostic software to test the drive?
 
What do you get when viewing the partition table? You mentioned Linux, did you originally apply a Linux filesystem or partition type? What happens when you try to mount the volume?

You can try hitachi drive fitness test, works with most off brand drives.

download the iso file and use windows 7 disc image burner to write the image to a cd and then boot to the cd and run the extended test.

Yeah, that Hitachi hard drive fitness test (iso) didn't see the drive either. It will see the other 3 drives I have in the PC, but not the external hard drive I want to run the test on.

Any other Hard drive testing software out there?

Thanks
