I'm a newbie. Have installed CHDK on a 16gb card with two partions.
What camera are you using? Cameras released after 2010 do not need to use two partitions - they can boot from a single FAT32 partition.
When I need to empty my card I have to swap partions to get windows to reconize the right partion. Before setting the card back into the camera I need sdminste.exe to swap back again. Are there no other and easier way to do this ?
You can swap partitions in the camera using CHDK's
SD Card menu ->
Swap Partitions option.
So before you pull the SD card from your camera, select that and the PC will see the larger partition when you insert the card in your PC card reader.
To swap back afterwards, if you put the full CHDK distribution on both partitions, you will have a copy of ps.fi2 on the larger partition. You can thus put the SD card back in your camera, boot using the "Firmware Update" method, go to the SD Card menu, and select
Swap Partitions to restore the partition order. (Note that a few cameras do not support "Firmware Update" booting.)
