Is there any way to fix this or determine if the card is bad or the ports? I've tried switching the port it is in, but I get the same message, which seems to point to the card, but why might the card go bad? I've also pulled the batteries out of the calc and let it sit for about a week, but I still get the invalid card warning.

Thanks!

Try carefully cleaning the contacts on the card (carefully slide the shutter down first) and clean with alcohol or contact cleaner. Be sure to not leave residue from the cloth or Q-tip on the contacts. This has worked on a ROM card that had similar problems many years ago.

Did the card/port contacts get wet at any point?
