Your hdd is death you need to recover your data
Here's how :
Remove from the HS PC hard drive.
Put it in a freezer zip bag. (Take a quality bag that is your life's in this drive.)
Place the hard drive, and packed in another zip bag.
Put the package in the coldest part of your freezer.
Allow at least 12 hours.
Once fully cooled, replace your hard drive in your PC and start to retrieve your valuable data.
At one point the drive will work again more.
Repack it, and put it in the freezer for 12 hours.
You will repeat the process until you have recovered all your data.
Or until your hard drive finally gave up the ghost.
