Does anyone know why this might happen? Sometimes I have to re-start to have the computer read the SD card? I have gone into My Computer and refreshed the page but that doesn't help.
in this removable disk miss the device. try that : right click with my computer -properties - hardware -device manager - double click with disk drives (there is usb -cf ,ms ,sd , sm reader) - right click with usb cf reader -update driver -no, not this time - next -install from a list or specific location( advanced) -next - don't search i will . - next - click show compatible hardware - click in this hardware (to make blue) - next (continue anyway) .and that is for all (ms,sd ,sm) . if still don't work try to install from your computer cd that device . good luck !
