Hi, I found out about CHDK on an episode of
Systm 
My camera is a SX100 IS and it uses a 8GB MicroSD with an adapter. I tried using a cheap multi-card reader and my PC just lags when I try to open the drive. I also tried connecting directly to the camera, but I don't get the normal root folders.
I read on the FAQ about some issue with cards larger than 4GB where I have to partition and do some stuff. How can I do this if I can't access the card? Do I need a special program?
Thanks!
