Data Recovery From an Unbootable Mac With a Damaged File System

Recovering data from an unbootable Mac with a damaged file system can be challenging, but is often possible with the right tools and techniques. As someone who has encountered this issue before, I wanted to share my experience and recommendations.

Assessing the Issue

When my Mac stopped booting properly and was unresponsive, I knew I likely had some type of file system corruption. This meant the directory structure and information about my files was damaged in some way, preventing my computer from starting up correctly.

The first step was to diagnose the extent of the file system damage. I booted to recovery mode by holding Command+R while restarting. From there, I was able to access Disk Utility and run First Aid on my drive. This found and attempted to repair the file system errors. However, it was unsuccessful, confirming serious file system corruption.

At this point, I knew I would need data recovery tools to copy the files off the drive before I could reformat and reinstall the OS.

Evaluating Data Recovery Options

I researched different data recovery applications and services that could help rescue data from the unbootable drive. Here were the main options I considered:

• DIY recovery software: Apps like Disk Drill and Stellar have features to reconstruct damaged file systems and copy files from drives that won’t boot. This was the most affordable option but required technical skills.

• Local data recovery service: I got quotes from a few local IT shops offering data recovery. Their cleanroom facilities and experts could image the drive and extract files. However, this was expensive, costing hundreds to thousands of dollars.

• Remote recovery service: Companies like DriveSavers offer mail-in data recovery services. I could ship them the drive and get an image file of its contents to restore lost data. Prices started around $500-700 but could go up depending on complexity.

Attempting DIY File System Repair and Recovery

To save money, I decided to try using Disk Drill’s data recovery myself before resorting to a paid service. Here are the steps I took:

1. Booted to Disk Drill from an external bootable disk. This bypassed the corrupted file system entirely.

2. Ran Disk Drill’s Recovery Vault scan on my internal drive. This found lost file records and metadata from the damaged file system.

3. After several hours, the scan completed and I was able to browse and restore recovered files. I saved these to an external hard drive.

4. I used Disk Drill’s tools to try repairing the file system as well. Unfortunately, the deep corruption couldn’t be fixed with DIY software.

Turning to Professional Recovery

Since I couldn’t fully repair the file system myself, my last resort was to turn to a professional recovery service. I decided to use DriveSavers for a remote recovery. Here is how that process went:

1. I removed my Mac’s hard drive and packaged it securely. DriveSavers provides shipping materials for this.

2. I filled out a case form on their website with details about my drive failure and the types of data I needed to recover.

3. I shipped the packaged drive overnight to their facility and was provided with a case number.

4. In 2-3 days, DriveSavers imaged the drive and uploaded a copy to my personal secure portal.

5. I downloaded over 300GB of recovered documents, photos, and other important files from the drive image.

6. Once I verified all needed data was recovered, I authorized DriveSavers to ship my original drive back.

In the end, going with a professional recovery service got my files back successfully. But trying DIY software first saved me money instead of immediately paying over $1000 for a full-service recovery.

Key Takeaways for Data Recovery from Unbootable Mac Drives

Here are my top lessons learned from dealing with file system corruption and data recovery on a crashed Mac:

• First Aid in Disk Utility can find but often cannot fully fix severe file system damage. Don’t rely on it alone.

• DIY recovery software like Disk Drill can recover lost files but cannot always completely repair the file system.

• Always keep backups, as they make recovery cheaper and easier. However, data recovery services can still rescue data when all else fails.

• Remotely shipping drives to recovery pros like DriveSavers is more affordable than in-lab services. Evaluate costs before choosing a solution.

• If DIY tools partially recover files, save these to another drive before sending for professional recovery. This avoids paying for duplicate data.

Recovering data from a non-booting Mac with file system corruption takes patience and the right tools. But even in the worst scenarios, hope exists for getting back lost photos, documents, and other irreplaceable data by utilizing recovery software, services, and cleanroom expertise. With the right approach, you can rescue files from an unbootable Mac and get back to business.
