Ok guys, I have a 6th gen (80gb 1.1.2 version) iPod, and I'm trying to install an iflash with a 256gb SD card. I am using an iMac (OS X 10.5) and the sd card is formatted Fat-32; when the iPod is connected normally, it mounts fine. When I put the iPod in DFU mode (hold menu+select until screen turns off), it doesn't mount, and the Rock box utility won't recognize it. System profiler shows it as a usb DFU device with the id #1223, so I know it's in dfu mode. What am I doing wrong?
