Hard drive in caddy doesn't show up on My PC/Computer anymore

I had to take hard drive out to do some work with another hard drive. After I was done with that, I put my original hard drive back and now it doesn't show up on My PC/Computer anymore (file explorer).

It appears to be "working properly" in the Device Manager. Besides, when I open the disk management tool and see yellow exclamation mark and no size or any other info about the disk.

I cannot format it since I have very important files inside. Is there any other solutions that I should try before I give up? I can hear it working, it doesn't seem to be completely dead.

Any hopes?

And interestingly this program called Crystal Disk shows it status without a problem

Solution 1:

I have solved it finally. Just right clicked on the hard drive on disk management window and then clicked import foreign disks.. Now I can go to sleep!
