Mac Data Recovery Guru 4.0.2

Mac Data Recovery Guru works by employing content-based file scanning. This is a different approach to traditional forms of data recovery which attempt to repair the device in question, which when they go wrong will write over the data you were trying to retrieve in the first place. Our method opens the device in read-only mode, and will search through the entire device for files, or pieces of files, that are present. It reassembles the data it finds into regular files on the fly. Sound complicated? It is, but after years of refinement it appears to the user as a seamless process, and is as easy as browsing through your regular files in the Finder. In fact, it looks almost the same.

Frequently Asked Questions:
What kinds of devices do the data recovery products work on?

The short answer is any device which acts as a drive on your Mac. However the device does not have to be visible in the Finder as the Recovery Guru line can see and scan devices which OS X does not show. To see if your device is usable, open the program and click on the “Drives” tab on the main window. It will show you everything that can be seen.

The long answer is that it works on devices such as these (this is not an exhaustive list, but a series of examples):

Disks: Macintosh disks (HFS filesystems, HFS+, HFSX filesystems), Windows disks (NTFS, FAT filesystems), Linux disks (Ext2, Ext3, Ext4 filesystems), Unix disks (XFS, UFS filesystems).
Digital Cameras: (Kodak, Minolta, Nikon, Canon, Fuji, Olympus, Sigma).
Mobile Phones: Android, Nokia, Motorola, Palm, Dell, Hewlett-Packard, Samsung, Sanyo, Siemens, Sony Ericsson, Panasonic, Kyocera, Blackberry.
Miscellaneous devices: USB pen drives / USB flash storage / USB memory sticks, Memory Cards for cameras and portable devices, CD’s/DVD’s, MP3 Players, PlayStations, X-Boxes, Wii’s, Palm devices.

What if my device is not appearing at all?
Mac Data Recovery Guru can often still see it and recover deleted files back from it, even in some severe cases. Click on the “Devices” tab next to “Volumes” to see every device that is available. Download the free demo and see.
What if I have completely formatted my device?

It makes no difference if the device has been completely formatted 100 times or still has a filesystem. Our programs will search through the entire device irrespectively and pick up any data remnants, which formatting a drive does not affect.
Can anything stop it?

The only things that can typically deter it are the following:
One is if the file you want back has been written over since you deleted it (but your chances are usually pretty good, if you run the demo you will see many files that you deleted years ago).

Two is if the device has been secure-erased, in which case nothing can get it back, with the exception of some data on some SSD drives.
