I have a Dell Inspiron 6000 laptop. It has an SD card reader built in to it, but it does not seem to be working. I checked in the device manager and it says that it is functioning properly. However, when I put the SD card in the reader nothing happens. I figured that it would just show up in explorer, but it doesn't. The card I am putting in is the one that came with a digital camera I just purchased. It is a Canon Multimedia Card. Any ideas to solve this problem would be greatly appreciated. Thanks.
