Is there a way in which I can make old CDs and DVDs unreadable? I have several dozen to throw away and suddenly realised what a lot of personal data they contain. Would a single large scratch across the surface be sufficient? I don't fancy going through them individually to delete the data.
Health and safety are not going to like this, but dropping them in a lawn mower with a 'contained' box provided total destruction in rapid time. Goggle,gloves, keep fingers away from rotating blade and outside testing ground recommended ;o)
