Been trying to use a card reader i got for my microsd kingston 2gb. When i try to copy big files onto the card it gives me i/o errors. Tried formatting, formatting to different file system (fat32). There aren't any company drivers or firmwares. It worked straight out of the box on vista 32bit as well as another xp 32bit machine. Just wondering if there are any fixes or anyway to report it to microsoft. Thanks.
