I have never had to use DiskWarrior. However, if I ever have a problem with my M1 drive, or any other formatted APFS drive, it will (hopefully) be good to know DW and others like them will be able to at least give us a real shot at saving a drive.
Disk Warrior quite literally saved my career.
I had gone to the Caribbean to shoot a destination wedding and when I arrived, the couple asked me to document the entire trip, not just the wedding. I hadn’t accounted for a week of photos and couldn’t find a place that sold CF cards but no problem, I had my MacBookPro with me. I could load the photos in Lightroom and wipe the cards.
*RECORD SCRATCH*
Narrator: “Don’t do that kids. Now back to our story…”
On the flight back, my Mac went blank. Checked the battery, 70%. Tried to boot up. Wouldn’t go. We landed and I plugged it in. Booted into safe mode: “No hard drive”. Gulp.
After weeks of agony and swapping between telling the couple or getting plastic surgery and running away to Europe, I got advice about transplanting the platters to an identical drive enclosure. That worked — partially. My Mac recognized the drive and saw that there was data on it. Couldn’t make sense of the ones and zeros.
More advice: recovery pros use Disk Warrior. Hastily paid what I thought was an exorbitant licensing fee which turned out to be the most value I’ve ever got out of an app. Within minutes, the directory was rebuilt and there they were: every single photo from the entire week, just a few non essential pics with scrambled digital artifacts.
Currently, I have an encrypted APFS drive that my iPad Pro kept unmounting unprompted. After so many times, it eventually corrupted the directory and won’t mount. Nothing super essential but recovering the drive would save me a lot of time. Another app is asking for hundreds of dollars to recover the drive and can indeed see the files. I’d rather give my money to Aloft than give into ransomware. Patiently waiting for version 6 which I’ll gladly keep in my toolbox for the future.
