Hi Jim
If it is a SATA hard drive I suggest you get a 3.5 inch SATA Hard Drive Enclosure. [ there may be a label on the drive to confirm this ]

Be very careful when ordering - laptop hard-drives are 2.5 inch and the enclosures are very different.
You don't have to order from Amazon - obviously
So - make sure it is SATA and 3.5 inch
When you get your enclosure it is a simple case of opening it up and popping the drive inside.
Then connect up the cables.
3.5 inch drives usually need a mains connection.
Click here for video of how to connect up.
Once connected you can treat the drive as you would a USB memory stick.
You can format the drive and use it for storeage if you wish.
[Obviously don't format until you have all of the data off the drive that you need]
We are assuming that there are no problems with the hard-drive.
If there are - you may not be able to get at your data.
