Why does the the USB-SD Creator need to make a partition on the USB stick or SD card when run from windows.
It doesn't appear that Windows is capable of working with partitions on these types of devices.
Because it just writes disk image to USB disk/SD card. Nothing more.
To make the tool user friendly could the windows USB-SD Creator tool be programmed with the ability to reclaim the USB stick or SD card for use in windows (i.e. unpartition for dummies).
Yes, this function is on my todo list and already done some initial work. Together with faster writing speed (double than what is now), write verify option and backup function. But no ETA (not in the mood for anything at the moment).
For now SDFormatter must be used to init device to initial state.
