Before you learn how to recover deleted data on Mac OS X, it's important to understand what deleting a file means. When you delete a file, the operating system simply erases the entry – not the contents of the file. This means that the space is now free to be used for new data, which is why you typically can't find a file after you've deleted it.
Should you accidentally delete some important files, there are steps you can take to recover them.
First of all, do not write any new data to the hard drive or device from which you have lost your files. Ideally, do not use the disk or device at all. Next, you may consider using a professional Mac Data Recovery Software, which is compatible with Mac OS X, to retrieve your deleted data.
Fortunately, there's powerful Mac data recovery software - Data Recovery Wizard for Mac to the rescue. It can effortlessly recover deleted files on Mac OS X for you. Typically, it works in two simple steps: scan the disk/driver to locate lost files and then recover deleted files from the Mac Trash.
Next, let's go through a detailed walkthrough.
Note: You can create a backup first by clicking on “Disk Backup” on the left. The software will recover the deleted files from the backup image, which prevents further damage to your disk and data, making it safer and more reliable.
Step 1: Scan the deleted file
Select the hard drive, external disk, or SSD from where your data and files were deleted, and click “Search for Lost Files.”
Step 2: Filter out missing files
The software will perform a quick and deep scan, trying to find as many deleted files as possible on the selected volume. Filter the required files by the “Type” and “Path” options.
Step 3: Recover the deleted files
Preview the files by double-clicking them, and then click “Recover” to get them back.
Apart from retrieving deleted data from Mac OS X, Apple Mac OS X Data Recovery software retrieves various types of files, including images, music, videos, emails, and documents lost due to virus attacks, formatting of hard drive, and so on. Give it a try!
