It’s funny how there are certain kinds of knowledge about computers that no one should ever want to have, because it means something bad has happened. Recovery of deleted files is a perfect example. If one is researching deleted data recovery, then they likely have just erased a very important file that they cannot afford to lose. I suppose the good news is that in the case of erasing files, they can be recovered most of the time with a well designed program. And, it isn’t hard to tell a better application from a lesser one in the area of data recovery. Just the language used on a recovery software company’s website is enough to tell most savvy computer users how good their product is.
