*******CHDK is active the cam will not be aware it's locked, and should happily delete, from either the Canon menu or with CHDK's filebrowser. *********
I usually use the card reader to delete the pix and it would not work with the card locked, is that normal?
********
if you are starting CHDK the 'firm update' way, no, you can use any card that your cam recognises.
however, if you start CHDK the 'bootable' way (using the card lock) you can normally only use cards up to 4 Gb,
because this method requires a FAT16 file system, and the max. size of a FAT16 file system is 4 Gb.

So if I start the camera with the card unlocked in review mode and go to firmware goto update to the newer 1,1x version and then turn the camera to the take pix position I can use a large SD disc correct?
Thanks
