Should I back up my hard drive before I do this? This process won't delete anything off of it right?
Thankyou for the response
If you do not have a backup of the data on the drive, the very first thing to do is make one, NOW. Remove the drive and mount it in an external case -- connect it to a working system by USB and back up your data.
There is a very good chance the drive is failing -- you will need that backup sooner rather than later.
Once the data is backed up, you can proceed with the rest of the instructions.
