Fix 2: Make Sure that your System’s SATA Cables are Connected Properly

If you are using a PC not a laptop then you should check the older SATA cables of your PC. Make sure it is in working condition and connected properly.

This step is only for those users who have experience in dealing with internal hardware connectivity scenarios.
