Everybody loses some files that they want to recover at some point, and because of that mac file recovery software is now highly sophisticated. It is so advanced that things we would have considered impossible a few years ago now look easy. You can just select a disk and click Scan and suddenly start to see thousands of deleted files that you can recover appearing in front of you. Mac Data Recovery Guru is the only software that will generate thumbnails of the recoverable deleted files for you to view in realtime, so you can instantly what can be recovered, for free. Browsing deleted files in Mac Data Recovery Guru Mac Data Recovery until recently Deleted file recovery used to be done by reading the filesystem on the disk. If it were a Mac OS disk for example, then the HFS+ filesystem would be interpreted by the software, and an analysis would be made to try to determine what data was previously present before the deletion was performed.

Undelete files and recover lost data in a few clicks. In this way, each different filesystem would be developed for and interpreted in its own individual way, and each filesystem would have its own success rates and caveats. The success or failure of the file recovery attempt was also generally based on the state of the filesystem at the time. If the filesystem had been heavily modified after the file deletion had taken place, then there would be less chances of being able to undo that deletion. Likewise if the filesystem was heavily corrupted or if it had been formatted, that would often mean that no file recovery would be possible. If the disk had been formatted, then nothing would be recoverable. It did have some advantages; the folder layout and filenames would sometimes be preserved. Sometimes it would result that getting files back was a quick and painless process. So while it was not so reliable, when it did work it could be very convenient. This method is generally not possible these days, because filesystems have become more complex, and also because when it comes to deleted file recovery people demand functionality above all else. How to recover deleted files on your Mac in modern times Now data recovery has become about pattern recognition of individual file types. This has the advantage of making the recovery more robust and consistent because it is no longer dependent on the filesystem, so it makes no difference if a disk has been formatted or not. Now the only requirement for a deleted file to be recoverable is for it to be present, irrespective of the filesystem. It also makes it filesystem independent. It works on hard disks, USB flash sticks, USB hard disks & SSD’s, SD Cards, digital cameras, Android phones & tablets, or anything else that can be plugged into a Mac. OS X does not even necessarily have to be able to mount the device (so it can work on devices which do not show up in the Finder). It will work on anything that appears in Disk Utility. (Technically speaking: The only requirement is that OS X provides a POSIX node, for example /dev/rdisk3). Therefore you may be surprised to find that it will recover data from devices that do not show up as a volume. And since it is fault-tolerant (which gives it the capability of scanning around bad sectors), it can even be used to recover data from faulty media, which is sometimes useful even if the files have not been deleted, because it will successfully read and extract the files irrespectively. In 2016 Mac Data Recovery Guru added the feature of being able to scan used space (ie, files) as well as deleted space. So now if you have a disk image that will not mount, or some other file or folder with data inside it that you would like to extract the contents of, it is possible. This also opens up some forensics capabilities of the software as it extracts and decodes everything. If you run it over your browser history, for example, it’ll extract all the text and images from it as well as other file types. This is also useful for digital forensics. The way deleted file recovery software works these days is by reading every byte on the volume, and as it reads through it searches every byte on the disk for common patterns in each individual file type that it supports (or for patterns in general, for example it can recover all ASCII text found anywhere on a drive). If it encounters the start of a recognizable file it will record the location of that, and then search for whatever middle parts of the file that it can, and search for the end of it to finish it. Once it has a good idea of what the entirety of the file is, it will provide a real thumbnail preview of that file, and display it as an option to be recovered. This happens in parallel, with interpretations of the same data segments on the disk being interpreted and displayed as different files, and this can occur thousands of times per second.
