Top 5 Best Free Data Recovery Apps for Mac OS X
The best free data recovery software for Mac available online is described below. These five applications vary in their characteristics. However, all share one commonality, they are free, and therefore useful for the casual user.
#1. Disk Drill
Disk Drill is the free top data recovery app for Mac OS X. Disk Drill Basic, in addition to having previewing capabilities for recovered files, contains several other functionalities, such as Recovery Vault and Guaranteed Recovery, lost partition restoration, boot disk maker and so on, which make it one of the best Mac data recovery software applications available.
Recovery Vault is an advanced extra layer to the Trash Bin that keeps a reference to deleted data. Guaranteed Recovery is a background service that saves a copy of each file to a user-specified folder. Both data protection modules substantially reduce the possibilities of permanently losing critical data.
Disk Drill works on internal and external hard drives, USB flash drives, SSD drives and many other appliances that can be connected to a Mac, including iOS and Android devices. Its last version has an extensive database of file signatures that can be restored from drives even after formatting, and uses very efficient and fast scanning algorithms. Disk Drill is constantly updated and supported by its ever-growing team, and covers cases of data corruption resulting from loss of power, or removal of a device without first unmounting it.
In addition, it also includes image file creation capacity, providing the user with the ability to recover lost data from a byte-to-byte clone version of the device/partition, without having to risk the original storage source. In addition to that, multiple extra tools, like Duplicate File Finder, or Emergency Recovery Boot Drive, are available for free.
PhotoRec is not the most powerful free Mac data recovery tool, but it has the advantage of being open source. This basically means that not only the application, but also the source code is available to the public.
PhotoRec can work with OS X, Linux, Free BSD, Net BSD, Open BSD, and Windows. It can recover the most common file formats, such as JPEG pictures, MP3 audio files, OpenDocument and Microsoft Office files, PDF documents and ZIP archives. Files can be recovered from different devices such as digital camera memory cards, USB flash drives and hard disks.
This free file recovery Mac app uses a powerful technology known as file carving. This method consists of two steps. Firstly, it searches for the data block or cluster size. If the file system is not corrupted, this value is obtained from the superblock (ext2/ext3/ext4) or volume boot record (FAT, NTFS). If this is not possible, the app checks each sector of the device, and using the first ten files found, it calculates the block or cluster size. Secondly, the app reads the device, block by block/cluster by cluster, checking against the different file signatures available in the app’s database, thus assembling and recuperating the available files. Though it’s unclear how many of those file signatures are known to the app.
Overall, it is a nice tool to use when in need to recover some personal files, without having to resort to a professional application.
#3. EaseUS Data Recovery Wizard
EaseUS Data Recovery Wizard is another one of the best data recovery Mac software applications. The developer has released three different versions: free, Pro and unlimited. The free version is limited to a maximum of 200MB of restored data.
This free data recovery software can recover data from Mac notebooks, desktops, hard drives, USB drives, SD cards, memory cards, digital cameras, etc. It works on internal HFS+ drives, and on FAT/FAT32 file systems used in USB flash drives and external hard drives connected to an Apple computer. It recovers file formats most commonly used in image, video, music and document files.
It is mostly designed for recovering lost files due to unintentional deletes or drive formatting.
Summarizing, EaseUs free data recovery tool is a handy app designed for casual unintentional file deletions.
#4. Softtote Mac Data Recovery
Just like other apps in this list, this free data recovery software Mac comes with free technical support.
Softtote’s app can recover lost files from internal and external hard drives. File types include ONLY bmp, jpg, png, tif and mp3. It works on devices supported by NTFS, HFS/HFS+ and FAT file systems. The application has the capacity to preview file details, such as image size and creation date before recovering them.
In brief, Softtote’s software can be included among the best data recovery software Mac, and even though it is not so well known, it deserves a try in case of accidental file loss, but mind the limited set of supported file types.
#5. MiniTool Power Data Recovery
This data recovery Mac software has a personal edition that is free for use only on one computer and with a maximum restore capacity of 100MB. Is that why it’s called a Mini Tool? Possibly. The developer also offers commercial, enterprise and technician editions of the software.
MiniTool can recover photos, music, videos, emails, documents, and other types of data from Mac computers or other common storage devices. The free version only offers support via email.
This data recovery software for Mac works in four different modes. The first, “Undelete Recovery”, can be used to quickly recover data lost due to accidental deletion. The second, “Damaged Partition Recovery”, recovers lost data from existing partitions. The third, “Lost Partition Recovery”, recovers lost data from lost or deleted partitions, subject to success in finding them. And finally, the “Digital Media Recovery” mode, recovers multimedia files from portable storage devices.
Overall, MiniTool offers a valid option for the casual accidental delete, in cases that don’t involve big volumes.
The Bottom Line?
We recommend going with Disk Drill, as it delivers on its data recovery odds. This awesome data recovery tool is backed up by good looks, a more intuitive user interface and a ton of free disk tools that may become handy for any user.
