Anyone have their sd card get fouled up and have to format it? Out of the blue last week my Droid said couldn't read sd card and needed to format it....lost everything on it as I couldn't back it up to my pc. Thought it was weird when it happened and haven't had any troubles since. Hoping it was a fluke as I'm past my 30 days, but I've really had no other issues so I don't think my phone or card is defective. Would maybe knocking the card loose from a fall be the culprit?
