I have a windows XP PC. Problem how to open 4GB MMC / SD card. With my card in the reader slot, after clicking on the MMC/SD drive image in "My Computer" , I get the message " The request could not be processed because of an I/Oerror." How do I get my card reader to read this card.
Is your card reader suitable for 4G size, some earlier ones were not? Have you a smaller one to try?
Always pop back and let us know the outcome - thanks
