Thanks, I'll try those things. One card is a Sandisk Xtreme 512 MB. I should be more clear. Both cards and the iPod work fine independantly. The problem happens when I import from one of them, eject the card properly, and insert the other card or the iPod without closing iPhoto in between. The second import shows an empty card, until I restart iPhoto, and then it works fine also. For example, I plug in the sandisk, and import 20 photos, eject it, and then connect my iPod (60 GB color screen) and it says it is empty. I close iPhoto, and re-open it, and then I can import from the iPod. This is by no means a show stopper, but it is a little annoying. BTW, it is a Canon digital Rebel XT.
