Repair your hard drive components.
If things are much more dire than anticipated and you have to open up your hard drive, you might need to actually physically repair some components. This isn’t as simple as order Data Recovery Raid, but fixing it on your own is still possible. Make sure to pull up the exact diagram of your hard drive online and then begin testing to see what part of your hard drive failed. If your circuit board or spindle motors failed you can order replacements online. Then, being very careful, you will want to install these. Wear gloves and be aware of the fact that your skin is oily and can mess with components further. Only pursue this option if you don’t mind voiding your warranty.
