How to recover lost files on OS X
Disk Drill is the leading data recovery software for Mac. It is easy to install and run. You don’t need to be a computer whiz or have any special knowledge to use it.

A lot of times when you have lost, deleted or mistakenly removed files from a disk or drive, the files are still there — you just can’t see them. Disk Drill finds this “invisible” data and helps you recover it. It uses three different scanning methods, plus several disk repair algorithms, to fix your drive (if needed) and allow your Mac to recover its deleted data.

Below you can find a brief overview of how to recover your lost Mac documents. For detailed tutorials, see How to Install Disk Drill and How to Recover Lost Data with Disk Drill Basic in our Knowledgebase.

#2 Launch Disk Drill

Once you have installed Disk Drill, go ahead and open the program. The first time you open, it will ask you some questions. We recommend leaving the boxes checked and proceeding to the main window. There you will find all the drives that Disk Drill has detected that are connected to your Mac. Select the drive (and partition if needed) where you wish to recover your lost data on Mac OS X.

#3 Scan Your Drive

To recover lost images on your Mac (or other lost data files), you will first need to scan your drive. Click the Recover button next to the drive in question and Disk Drill will run through all of its scanning methods, one at a time.

#5 Identify Lost Photos and Images

Disk Drill is particularly good at recovering deleted photos on Mac OS X. If you are looking to recover deleted images, you can usually identify them in the scan results by using the file type drop-down menu and selecting “Pictures”. This will narrow down your search results to those with image file types. Then you can preview the images and determine which ones are good candidates for recovery.

#6 Upgrade to Disk Drill PRO

Once you have previewed your files and identified the deleted data that you wish to recover, you are ready to upgrade to Disk Drill PRO. Check out available Disk Drill editions and proceed with the upgrade process.

After upgrading, head back to your scan results and check the box next to each file you wish to recover, then click the Recover button. Recover Lost Files on Mac OS X

Disk Drill looks into details

When Disk Drill needs to look into the core structure of the files it doesn't care if your drive is FAT, NTFS, etc. Our app for lost data recovery on Mac applies all of its knowledge of file signatures to be able to put the remaining fragments together. Once it identifies the binary signature it easily recovers lost files like .jpg, .doc, .xls, etc.

    You guys saved me $$$ this evening. I thought I had lost a whole day worth of footage from a shoot I was at on 9-11-15. I had a drive go bad today that I didn't backup like I should have done and spent all day looking and searching for any kind of backup and recovery software. I accidentally found you guys on the web and figured, hey it's free...why not try it. Well, 20 minutes and 52 gigs later, I'm back in business.
