if you are running leopard and your boot camp partition is in ntfs format it is not as simple as the get info copy and paste method... stick in a usb stick in mac os x, and paste the icon you want your windows drive to be on the usb stick (copy your desired icon, get info on usb stick, select current icon in top left so its highlighted, paste icon)... then boot into windows, open the usb drive and set folder to show hidden files (tools > folder options > select view tab > select show hidden files and folders)... then drag .VolumeIcon.icns and ._ file into your c:/ .. then hide hidden files and folders in windows again then reboot into mac os x and see the nice new icon... (note this does not change the icon on the boot loader screen, if anyone knows how to do this let me know) i attached pictures of my icons on my mbp
