Best advice, if you haven't already, try backing up any important data, maybe find an external USB hard drive, boot from your emergency repair disk and backup your files. Then find the make/model of your failing hard drive and go to the manufacturer's website to see if they have some sort of diagnostic utility you can download and run on it. It could be time to look for either a replacement hard drive or alternate boot methods.
