Thanks for the replies gents and fossils
Were the floppies upgraded at all during their life, as in faster read/write abilities and noticeably greater capacity such as happened with USB stick storage in the last 5 years ? Were they susceptible to corruption by being near magnets (speakers and the like) ? For that matter, were they prone to losing data that seems to plague flash cards at times when being plugged/unplugged from various electronic media ?
