Have you experienced hard drive failures? Quite often?
Hard drive failure is inevitable and there’s actually nothing you can do much about if you’re unable to gauge the early symptoms of its failing.
Did someone say early symptoms? What are they?
Hard drives become non-functional with time and it could be your backup drive and the irony is that hard drive failures happen more often then you may imagine. It can occur due to physical, logical, or mechanical failure in the hard drive. Any kind of disruption in the hard drive’s master boot record can damage the contents stored in it. However, if you’re able to gauge the early signs of your backup hard drive’s failing, then you are in the best position to prevent data loss.
If you suspect that your backup hard drive is failing, then the best course of action would be to transfer all the data stored in it to another drive and prevent losing crucial data, provided you are able to detect the signs.
What if you’re unable to detect the signs?
Here’s how you can restore data on Mac when the back drive fails.
Reconnect the backup drive
Sometimes, when you plug in your backup hard drive in your Mac computer, then it fails to mount. Check whether the drive is connected properly as there might a chance that it is not receiving enough power supply. Moreover, if the hard drive lights up, check whether the cables or the USB port is not faulty and try connecting the backup drive using another power cable.
Check whether the hard drive icon is removed from Mac desktop
Another reason could be that your Mac is not set to mount external hard drives; therefore, to mount the external hard drives, go to Finder < Preferences < General and ensure that the check box next to external disks is selected.

Repair the drive using Disk Utility
Using Disk Utility, you can address several issues such as external hard drive is not showing up, a file is corrupt, any application crashed unexpectedly, etc. Restart your Mac computer, and press and hold Command + R keys until the Apple logo appears. Select Disk Utility, and then select the backup hard drive and choose First Aid.
If the hard drive is about to fail, then transfer all the data from it to another drive.

Imaging the drive using Disk Utility
Even after running First Aid option on your Mac, you’re unable to repair the backup drive, try imaging it. Restart your Mac computer and hold down the Command + R keys till the Apple logo appears. A window with macOS Utilities will appear, select Disk Utility option. From the given options, select Restore.
