I once tried a similar thing with a memory stick adapter and a memory stick. It didn't work in the PTR1. If you can't use your SD card for something else, I'd definitely try to return it. Why shouldn't a dealer take it back, you haven't used it after all and it is still a new card. For the PTR1, you should use a CompactFlash card, Sandisk CF cards never let me down. <*** Michael Lang ***> --------------------------------------------------------------------------- To leave the list at any time, please write to <ptr1-users-request@xxxxxxxxxxxxx> with unsubscribe ptr1-users in the subject or the body.
