This can greatly decrease the chances of a file recovery in the case of a simple deleted file recovery. Lastly, Apple’s more recent line of hardware has been shipping with built in SSD drives which support TRIM, which is a mechanism whereby an SSD drive will write 0’s over data as soon as a file is erased. 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. 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). The only things that can typically deter it are the following: 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.Mobile Phones: Android, Nokia, Motorola, Palm, Dell, Hewlett-Packard, Samsung, Sanyo, Siemens, Sony Ericsson, Panasonic, Kyocera, Blackberry.Digital Cameras: (Kodak, Minolta, Nikon, Canon, Fuji, Olympus, Sigma).Disks: Macintosh disks (HFS filesystems, HFS+, HFSX filesystems), Windows disks (NTFS, FAT filesystems), Linux disks (Ext2, Ext3, Ext4 filesystems), Unix disks (XFS, UFS filesystems).The long answer is that it works on devices such as these (this is not an exhaustive list, but a series of examples): It will show you everything that can be seen. To see if your device is usable, open the program and click on the “Drives” tab on the main window. 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. The short answer is any device which acts as a drive on your Mac. What kinds of devices do the data recovery products work on?
