30 minute old Seagate 2tb hard invisible

In Windows device manager the make and model of the hard drive is visible , and I've uninstalled and installed it there and tried updating the drivers , but Windows Explorer file manager can't see it. Neither can it be seen from a boot into Paragon disk management CD.

A system crash while copying files to it caused me to pull it out of the USB port in order to try and unfreeze Windows . I now think I might leave been better to force shutdown windows, but that's just speculation.

Thank you for your time!

Can we assume this is an ordinary external hard drive in an enclosure?

Do you think it has been partitioned?

Do you think it has been formatted?

Do you think it has ever been given a drive letter?

Is it unseen in Windows Disk Management?

It's a consumer type all-in-one, not a independent enclosure with a hard drive slipped into it . I am sure it wasn't partitioned. I don't remember what letter it was assigned but I'm sure it was, as I was accessing it in the explorer file manager . Unseen in disk management but seen in device manager.

subsequent to the failure it couldn't be recognized even from a boot disk as unallocated space.

Thanks

Caledon - I have rebooted the computer and tried a second USB port and even tried it on another PC with the same results.

One curiosity though is that both computers identify drive in device manager as "Seagate Portable SCSI Device" . I would have thought that that designation applied to a different type of storage device

Thanks

Definitely does not show in disk management, in fact Windows will not even boot up if it is attached at start. Perhaps I should have mentioned that I actually caused this failure in the sense that I attempted to copy something while it was still downloading! This is what froze Windows

See if you can find a camera or smartphone camera.

Zbook, my reply seems not to have been posted. When I try to boot into bios I can't get past the opening screen unless I remove the external hard drive. Once I attach the external hard drive I cannot navigate around the bios screens until I pull the drive out
