Ways to Recover Failed Mac Storage Drive

1. Repair Mac Hard Drive by Using Disk Utility

Disk Utility is a native macOS application that can help you resolve Mac hard drive problems. If your Mac’s startup disk turns corrupt, then launch Disk Utility through macOS Recovery mode and repair the disk. Steps are as follows:

Step 1: Power on your Mac and immediately press and hold Command + R keys. Release the keys when the Apple logo appears. Your Mac boots into macOS Recovery mode.

Press-Command-and-R

Step 2: From the macOS Utilities window, click Disk Utility and then click Continue. The Disk Utility window is displayed.

Select-Disk-Utility

Step 3: From the left pane, select the startup disk: Macintosh HD. Click the First Aid button on the top pane, and then click Run

Step 4: Let the software repair the startup disk. Once the disk is repaired, there could be two possible outcomes:

i) Mac startup disk is repaired successfully: If Disk Utility repairs the corrupt disk successfully, restart your Mac and boot into Desktop normally.

ii) Disk Utility can’t repair the corrupt startup disk: One limitation of Disk Utility is that it can’t repair a corrupt partition map. To repair the partition map on a startup disk, you need to erase the Mac storage drive with a new partition scheme. But erasing the drive without taking its backup will cause data loss

In case Disk Utility fails to repair your startup disk, then try the next troubleshooting method.

2. Repair Mac Startup Drive by Using Single User Mode

Single User mode in macOS can be of great help to fix startup disk issues. If your Mac doesn’t boot, then use the file system consistency check (fsck) command in Single User mode to repair the startup drive. Follow the given steps:

Step 1: Power on your Mac, then press and hold Command +S keys. Release the keys when text appears on a black background. Your Mac will load the Single User mode

Press-Command-and-S

Step 2: In the command line, type the command /sbin/fsck – fy, then press Return.

FSCK-Mac

i. If Macintosh HD is healthy, it will display the message: “The Volume (name) appears to be OK.”

Single-User-Mode


ii. If fsck repairs the damaged disk drive, it shows the message: “File System Was Modified”. Re-run fsck command till the file system shows “The Volume (name) appears to be OK” message.

F-S-C-K

The fsck command quickly repairs disk errors in Mac storage drive. But it may or may not fix the corrupt startup drive entirely, if the corruption is beyond the built-in repair capabilities of macOS. In such a case, it’s better to go with the next method.

3. Retrieve Mac Data by Using Target Disk Mode

The Target Disk mode is an advanced boot mode that helps you access the failed startup disk on a Mac by using another working Mac. The method requires you to connect the working Mac and the failed Mac with a Firewire or a Thunderbolt cable. Once the Target Disk mode is implemented, you can easily recover files from a failed startup disk.

Steps to recover Mac data using Target Disk mode:

Step 1: For iMac or Mac mini, ensure uninterrupted power supply to the Desktop. For MacBook Air or Pro, connect the device to its charging port.

Step 2: Use a FireWire or Thunderbolt cable to connect both the Macs through USB ports.

Step 3: Start the Mac system with a failed storage drive and immediately press and hold the T key. Release the key when it displays a FireWire or Thunderbolt icon.

Step 4: On the working Mac, you’ll see the troubled storage drive icon on its Desktop. The ‘Macintosh HD’ will have a Firewire or Thunderbolt symbol on its icon.

Step 5: Once ‘Macintosh HD’ is mounted, you can use First Aid option in Disk Utility to repair the startup disk and copy files from the disk to a working external hard drive.

By using the Target Disk Mode, you can recover an unmounted Mac storage drive and copy the files stored in it.

Follow the next troubleshooting method in that case.
