Originally posted by OrchidJulie Some cards just don't make nice with some card readers... try connecting the camera directly to the computer using the USB cable. Turn the camera on, and the computer should see it as an external drive.
I have to do this for my boss's Leica -- putting the SD card into a reader literally crashes the computer, but connecting by USB works flawlessly.
Thanks for your reaction,
I already format the sd card and try to download some program to recover the lost files. See if that works..
Cheers,
