When you try to unrar corrupted files, does WinRAR *always* detect problems and stop creating the end file? Or could WinRAR create a corrupted file? Not 100% the same what it supposed to be. These issues have risen mainly from (non-scene) RapidShare/MegaUpload downloads...

If unrarring is "failsafe" (at least in WinRAR)... is there really need for .sfv files gererally?


Thanks
