Based on the upcoming 4MLinux 21.0 distribution, which should be out in spring 2017, this Beta release of the 4MRecover 21.0 Live CD ships with the latest TestDisk 7.0 and QPhotoRec 7.0 software, which can be used for recovering lost partitions or photos from damaged disk drives or SD cards of all types and sizes. As noted by the developer above, the 4MRecover Live CD is usually distributed as part of his 4MRescueKit project, which also includes the well-known Antivirus Live CD, BakAndImgCD, and 4MParted Live CDs. All these can be used independently of the operating system installed on the target computer.
