Hi all. I wanted to make a copy of an existing SD card, so, using Fred's SD Explorer, I attempted to do so. All files seemed to copy over to the new card (using drag 'n drop). I checked the new SD card and all files were there. However, when I attempted to load them in the 7000, no files were listed. Figuring that I'd done something wrong, I tried again...same problem. What do you think? Bad SD card maybe? BTW, my "master" SD card loads fine (thank God, lol).
