Hello everyone, my M10 is no longer recognizing any micro SD card. I could always reinsert the card once or twice and get it to read, but now it's not reading anything. The deck still works beautifully in every other way. Do you think it's OK to give that little slot a blast from a can of compressed air, something that is safe for electronics? I remember reviving a DVD drive in an old computer with a stream of hot air from a hair dryer, on the theory that it would dislodge dust and crud, but I don't want to try that with something that I value a great deal.
