No software recovery application will do what you want after a format operation has
completed. The reason simply is that formatting does not overwrite the files so
they can be recovered if they are readable and unless they are corrupted, you will
be able to save them, and possibly use them again. Only the file structure (FAT)
or "Table Of Contents" as we use to call it (and still do on CD's) are overwritten.
To wipe the whole drive of data (zero the drive) would take hours in some cases
and is un-necessary just to write new files to. Users don't want to wait for hours
let alone 15 minutes for a total reformat and overwriting of the whole HDD or partition/logical
drive.
I have pro recovery software and some used in forensics. None of them write to the
folder structure that the operating systems does, because it's destroyed along with
it's backup FAT. You have to filter recovered files with additional software to
sort through files, or at least I do because I can customize how I want to organize
the files as needed. It's only the recovery program's job to recover. It is then
your job to filter them and decide what you will do with them. The program can't
do that for you. ;-) Whether they are any good, is also impossible to tell. The
programs only give you a statistical probability of successful recovery. No guarantee
of whether the file is any good. That would be impossible, as is putting the files
back into the proper directory tree view that you saw when the operating system is
running...
