Okay, that drive is now visible in Disk Management, it looks like Windows was previously installed on that drive because there is an EFI (boot) partition on the drive, if you right click that 4657.33GB partition on that drive, do you get the option to change the drive letter and apply a drive letter to that partition.

On that mac, check the drive properties to see if that is the format of that drive.

Thank you for the screenshot, Disk Management can also not find that drive.
Connect that external drive up to another PC, is that drive working on the other PC?

What happened to that drive before it was no longer recognized, was it ever used on an Apple Mac PC, or did the drive ever fall?

Is that drive an internal or external drive, and what happened on your PC before the drive was no longer detected?

Right click your Start Button and open Disk Management.
Expand the bottom pane so all drives are visible in that pane.
Please provide a screenshot of that window.
