Disk Drill digs into details

Disk Drill's Deep Scan works through the raw data on your hard disk. When it needs to look into the core structure of the files it won't matter if your drive is FAT, or NTFS, or other. Disk Drill uses its wide knowledge of file signatures in order to put the remaining fragments together and undelete data on Mac the best way possible. Once the binary signature was recognized the app easily undeletes lost files like .jpg, .doc, .xls, etc.

What users and software gurus say

  • Raymond Jude Kaider
    I had two hard drives that were no longer recognizable by any of my Apple computers (or PC's, for that matter). The volume IDs simply did not appear in Finder. I bought Disk Drill only to recover accidentally deleted files and hoped I never had to use it. As a lark, I plugged in one of my unrecognizable hard drives into my MBP. Again, Finder showed nothing BUT when I started Disk Drill, after a few seconds, the drive's volume ID appeared within the app! I reopened Finder and amazingly the volume ID was there, too! I was able navigate the directory tree and recover any files I needed. I repeated the above procedure with the second hard drive and lo and behold, I had the same result! The drive ID appeared in the app and in Finder. I was able to see and save any of the files I wanted to to a more stable hard drive! You performed a miracle! You've won a fan for life!
