I have three external hard drives via suitable USB to my PC. I have been advised by a friend that I should not locate these on a shelf next to each other because of potential interactional damage.
Any advice please ?
Putting aside external drives just consider internal drives for a moment. Most of my computers have had at least two and sometimes three. Where are they - fitted one above the other by design without any problems so why should it be any different with external drives? Like Marvin42 now have external drives stacked up together with no ill effects.
