What type of electrical interference could cause a CF card not to record data? Would static electricity or a Piezoelectric charge make a difference? Or a magnet?
Thanks

Please ask a question I can answer.

Yes - any of the above can cause havoc on any type of electronics.
Static electricity, while extremely low in amps (5 mili-amps), is extraordinarily high in voltage (5,000 to 20,000). A shock like that can fry the CPU in a motherboard, the RAM cards, or a cf card, whose architectures are all very similar. Basically all the tiny transistors in those solid-state devices can be scrambled so that they do not properly operate.
Piezoeletric charges are also known to have very high voltages.
A magnet would do about the same thing to the transistors, it just accomplishes it in a different way.
Thanks Newton! The one thing I have thought about is if a item transmitting a certain amount of current located near a cf card can cause the cf card to go bad. Let's say I had a device that was either in contact with or very near another device that was encapsulated by a plastic housing....could the cf card go bad or fail to read any information. I'm trouble shooting here...just trying to get an idea.
Static electricity discharge into the CF card is the most likely cause of a permanent failure. The high voltage can break down the electrical barriers in the chip and cause it to fail.
Mechanical shock from dropping it would be another possibility. That might dislodge the electrical bonds between the innards and the external connections.
I don't understand where piezoelectricity comes into this picture.
A permanent magnet would be unlikely to do any damage to the CF since there is no magnetic process involved in its operation. A very intense AC magnetic field could perhaps induce problems.
