Do Not take it for granted that whatever should work because it says so on the label. 1) you need to make sure your device will boot to the USB stick or drive, ideally beforehand, & 2) you need to make sure you have a reliable external drive to store the backup data. That last has the advantage of not tying up your PC/laptop so you can get back to work. using a backup software bootable USB stick, then make a complete, sector by sector backup of the drive/partition - afterward you restore that backup somewhere else, & run recovery software on it. Īnd another way is to boot to another OS, e.g. Another way is to run Windows from an external drive, e.g. One way to accomplish recovery then is to plug the drive into another PC/laptop. Once a file is no longer indexed, there's nothing to prevent overwriting one or more of the chunks of data that make up that file, thus it is often recommended to stop writing to the drive/partition where the file was stored.

Recovery apps like iBeesoft Data Recovery find existing chunks of data & try to put them together as separate files. Data's stored in small chunks - working like a TOC or index, file tables list which chunks in which order make up complete files - with a regular drive those small chunks of data are not overwritten when a file's deleted, but rather it's TOC or index listing is removed - SSDs on the other hand run Trim operations to actually delete unused chunks of data.
