I'm glad you said Lexar because that's the other type card that has been working already in my cuddebacks.I had forgotten the name and the other 4 cameras are out at the farm right now that have some of the Lexar cards in them. I sure hope they are taking some pictures of a really big buck that has come onto the property. I'm trying to go to all 256mb cards but still have a few 128mb in use. All the new cards that aren't working (6 of them) that I just got are SanDisk 256mb. We're going to solve this mystery I can just tell. I think we've made progress tonight. Thanks for all the help. I'll let you know if the new card I buy works. If so, I think the problem is solved.
