How to Recover Lost Files on Mac OS

It’s happened to us all: deleting a file, folder or entire disk, then realizing that you’ve made a mistake. You reach for your backup-and you don’t have a backup. What now?

There are several deleted data recovery tools available to help in recovering deleted files under Mac OS X. Your chances of success depend on how the file was deleted and what you’ve done since then. Unfortunately you will also lose your original filenames, though some reconstruction is possible.

Deleting, Erasing & Partitioning

On the Macintosh moving a file to the trash, then Emptying the Trash, deletes the item. When you delete a file or folder you remove the entry for that item from the disk directory. Immediately after deletion the data still remains on the disk where it was but the directory says “that space is vacant.” As long as you don’t write anything new to the disk, recovery is usually straightforward.

If you accidentally delete something you need, if at all possible stop using the affected disk immediately.

Another way to delete a file is to use Apple’s Disk Utility to erase a drive. By default Disk Utility does a Quick Erase, which just deletes the disk directory and replaces it with a new empty copy. The underlying file structure on the volume is not changed, and any existing data remains in place until it gets overwritten.

Partitioning a disk removes all existing volumes on a device, then creates new ones with new disk directories. However like a Quick Erase, Partitioning doesn’t actually remove underlying data, it just marks the space as available. File recovery is usually possible on re-partitioned drives, though this will require a more thorough scan than with a standard erase.

A Secure Erase-typically a multi-pass process-writes new data to the disk and is deliberately destructive to old data. The utilities described here will not work if a Secure Erase is performed on your disk, recovery will require a forensic data recovery service.

Undeleting Files

All Undelete utilities require use of a separate recovery disk to which are copied recovered files. The recovery disk needs adequate free space for the expected amount of data. A hard disk, flash drive, another Mac in Target Disk Mode, or even an iPod, can be used to store recovered files.

There are a number of utilities available for this task, the one I’ve relied upon most is uFlysoft Mac Lost Files Recovery Tool for any types of files which you want to recover after losing them.
