I would recommend you get one of those "external casings" where you can put the disk into and run it as an external harddisk. If you have another hard disk available then pop that into the laptop. If you dont, then ask someone to borrow their laptop and check the external disk with a functioning laptop with proper flexibility (possibility to play, so to say).
Depending on the problem the disk is having, the solutions are different.
1. Try the external casing. What is the result? Can you find the disk, can you mount it? What happens?
2. If solution 1 fails, then you need to recover the data of a defect harddrive, you probably need help for that.
It could be that the disk connection in your laptop is defect somehow, either the power cable or the sata cable. If you move the disk to a case you will rule out any self fixable problems and can properly test it.
