Is it at all possible to reload overwritten saves on the Xbox 360 console when it comes to worlds on Minecraft Xbox 360 edition? I have a world which has been autosaved over and I would like the previous save to be recovered. How do I do so?
Popular modern filesystems will not go out of their way to actually overwrite the data on the disk or securely delete it when overwriting a file. It is therefore theoretically possible to restore the overwritten file if the stars are right (no blocks were overwritten since the file was deleted/overwritten). However, there aren't any utilities that run on an Xbox that could do this, and hooking up an Xbox HDD to a PC and finding software that will work with its proprietary FS may be more (legal) trouble than it is worth.
Sometimes it is best to cut your losses and move on.
