You've done some decent troubleshooting though.
One more thing you can try is to attach it with a different cable.
If the issue persists, then I believe you have a couple of options:
- Just RMA the drive, in case it is under warranty.
- Contact a data recovery company, if the data stored on it is really important. It seems that the enclosure is recognized but not the HDD inside. (showing up under Device Manager but not Disk Management). In that case, you will not be able to access the drive with software tools. You can try though.
Let me know in case you have some more questions,
