Hi there Collision pending,
You can try using some data recovery tool as DSzymborski suggested:

There is not really need to get enclosure or attach it to another computer. As you see it in disk management showing as unintialized, I assume that this is a secondary drive.
In case you can't access the drive with software data recovery tools, you may need to contact a data recovery company.
