Maybe I'm misremembering it but I don't think personal devices would be much affected. Apart from potentially damaging satellites, AFAIK the biggest danger is induction of big currents in powerlines and telecommunications lines and it could fry the components connected directly to them if they're not sufficiently protected from power surges (substations, network elements etc.). Any damage to data storage devices, computer chips and such would only be secondary, if the surge propagates all the way to the computer or server, which I find quite unlikely on a larger scale with all the surge protections we have. But someone correct me if I'm wrong.

I've heard some major techies will keep a spare unplugged microwave in their room with spare hdds inside incase a solar store comes. The same Faraday cage that stops waves from harming us should hopefully keep them safe if/when a Carrington event happens again.
