Disk Utility Failedįirst, Disk Utility displayed an alert I don’t remember ever seeing before:ĭiskWarrior succeeded after both others failed… Until recently, I’d have told you it was a three-way tie, with each of the three resolving roughly one-third of my disk issues over time. But, since the beginning of this year I’ve had three disk failures only one of these three apps could repair. That alone is reason enough to try it first. For another thing, who knows more about repairing your boot disk than Apple? And, for another ‘nother thing, it’s free (and you know how much I love free).īut when First Aid fails, as it sometimes does, I turn to a pair of third-party tools. When a disk fails or acts wonky-by not mounting when it should, or by disappearing from the desktop when it shouldn’t-the first thing I try is Disk Utility’s First Aid.įor one thing, it’s the only one of the three that doesn’t require you boot from a different disk to repair your startup disk (macOS High Sierra only). So, I also have more hard disk failures than most people.įor as long as I can remember I’ve relied upon the same three products when my hard (or solid state) disks go bad: Apple’s Disk Utility (free), Prosoft Engineering’s Drive Genius ($79), and Alsoft’s DiskWarrior ($119.99).
I have more connected hard drives (usually 7 or 8) than most people.
