I recently purchased a full size SD card reader to be able to read the SD cards in the two cameras my wife and I use. I’ve tested the reader with the 64 GB SDXC card that normally lives in my camera, and the SD card reader does not show the file system. All I see in explorer is a drive with the label SDXC, which does not open on a double click.

I’ve verified the SD card reader works correctly with a 16 GB SDHC, so I can only conclude that the issue is specific to SDXC cards. The card in question is a good quality card, it’s not a “no-name cheap” brand found on ebay, it’s from a reputable manufacturer: SanDisk, bought directly from their online store.
