To create image of the whole card (not just one Windows-visible partition), you can use dd for Windows (http://www.chrysocome.net/dd).

Run CDM as Administrator:

dd --list

Check which device is your SD card. In my case it was: \\?\Device\Harddisk1\Partition0. Partition0 refers to the whole disk, Partition1 to the first partition, etc.

Copy whole SD card to an image file:

dd if=\\?\Device\Harddisk1\Partition0 of=my.img bs=1M --progress
