Restore Mac Data
The question is, “Is there any way to restore Mac data from a failing hard drive?” Read this post to learn how to restore Mac data when the backup hard drive fails unexpectedly.
Have you ever experienced a hard drive failure? Hard drive failures are inevitable and there’s actually nothing much you can do about it if you’re unable to detect the early symptoms of it failing. Did someone say early symptoms?
What are they?

Hard drives become non-functional with time and it could be your backup drive. 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 on it. However, if you’re able to detect 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 connect an external hard drive to your Mac it fails to mount. Check whether the drive is connected properly as there might a chance that it is not receiving enough power. 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’s icon is removed from Mac Desktop
Another reason could be that your Mac is not set to mount external hard drives. To mount external hard drives, go to Finder > Preferences > General and ensure that the checkbox next to external disks is selected.

Repair the drive using Disk Utility
Using Disk Utility, you can address several issues such as an external hard drive not showing up, a file is corrupt, or an application crashed unexpectedly. Restart your Mac, 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.

Use Disk Image command in Disk Utility
Even after running First Aid 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.
