- No additional bootable unit
When Disk Utility & Recovery Mode Fails!
Due to a severe corruption of Mac hard drive (SSD or volumes), the Disk Utility (no matter Recovery Mode or Desktop Disk Utility) will ask you to backup the data and format the storage unit. Else, you will need to reinstall the macOS afresh. Taking the backup of an already corrupt storage unit is challenging task, and any clone/image software can fail while copying files. No backup tools guarantee the cloning of a corrupt hard drive accurately. Thankfully, there exists an optimum solution for SSD and hard drive recovery for Macs.
Conclusion
Dealing with disk errors is like playing with fire. One has to be a vigilante and one must assure that backups are in place. However, when the disk is badly damaged then leveraging Disk Utility should be the first step. You can also check your hard drive errors with Single User Mode. Nonetheless, don’t shy away from trying data recovery apps on your SSD when all means to repair the SSD give up.
