cb v9 works with a non sony hard drive works great
about the pen drive. my 32 mb pen drive would be seen by the codebreaker but would not do anything. i when to my computer stuck it in and formated it to FAT 16 and it worked like a charm after that/ its great having a usb flash so you can save all those files with 1 memory card
some one said they got cbodebreaker 9 working with duo2.
i have tested it will not work was there a diffrent version of the duo 2 with diffrent firmware
