How Does Data Recovery Work?

When a file is deleted under Mac OS X it is not permanently removed from its storage media. It is simply logically marked as deleted and its space made available for future use by the operating system. The Trash Bin is where recently deleted files are logically stored when first deleted.

Deleted files remain in the Trash until the bin is emptied. At the point that the bin is emptied the OS can use it for other purposes. Until the actual sectors of the physical disk that held a logically deleted file are used to store a new file, it can be recovered. Disk Drill uses cutting-edge scanning technology to take advantage of this feature of the macOS.

How Did This Happen?

There are a number of ways that you can wind up looking for deleted files. A common way is to inadvertently delete an important file and then empty your Trash Bin while cleaning up your computer. Sometimes, a system or application update can be the culprit. A virus or malware attack can be responsible for logically deleting files from your machine.

Whatever the reason your files are lost, Disk Drill is the right tool for recovering deleted files on your Mac. Download it for free and see what files it can recover for you.

    I’d like to say thank you as I have already recovered all my necessary files after I formatted over an HFS+ volume with FAT32. To be clear I had a 1TB external hard drive formatted as one HFS+ partition on El Captain. I accidentally ‘soft’ formatted the whole drive as FAT32. I used your application and recovered all my files since my last Time Machine backup. Again, thank you.
