After coming across a few corrupted files when importing to FCPX from my SD cards, I got to wondering what external influences might cause problems.
So first question is - would they be prone to corrupt if they come near magnets?
If so, I may have found a potential cause that I'd like to bring to everyone's attention. I have a recent Touchy MacBook Pro. The other day, I noticed that a USB stick I'd put down on the laptop to the left of the trackpad was sticking up at a gravity-defying angle. I realised the metal connector was being pulled down onto the laptop, and soon discovered there's a VERY strong magnet near the edge, (and a similar one on the right too). These are possibly loudspeaker magnets (although they're more under the wrist area than under the speaker grills).
Anyway, the point is, I sometimes rest my SD cards on the laptop before or after ingesting - so could these magnets be causing havoc? If so, it might be worth everyone being mindful of this and spreading the word.
Interesting theory about the speakers but as SD cards and flash drives do not store data magnetically they are generally not affected by magnetic fields especially the relatively weak ones in speakers. More details about this here-
In my experience data corruption in decent brand SD cards is rare and is more related to issues with the camera such as firmware that needs updating or a card that hasn't been reformatted in a while or corruption on the computer's internal or attached storage.
