It says 98% of the files are validated. Does that mean I will recover 98% of the files?
No, it means that 98% of the file types that are known
to iRecover appear
to be ok: by checking a number of file types and checking their state one can predict the state of all files on the disk, but it remains a prediction; the true test is to recover the files and check them.
I have made a purchase and trying to see if the recovered files are actually usable.
Let us know how things turn out.
