Thanks for the posts, guys. dfinch, that makes sense about the additional power. It's too bad if that's really the case. I assume there's nothing that can be done to boost the power output? Sentinel, that's a really good idea. Do you think my mini sd card hooked into an sd apater, and then hooked into the CF adapter would work? I searched for a mini sd to CF adapter and couldn't find any, and if I'm gonna go that route, I have 3 mini sdhc cards laying around that I would love to use. Thanks for the replies, Mike
