NEC ND 3520A rpc1 flash for mac

I have an external NEC ND 3520A with a LaCie casing. I connect it to my Powerbook G4 15" through firewire - I want to make it region free, so I downloaded the latest version and flasher. When I run the flasher for mac, it does not recognize my NEC - I enter the command to scan and it claimes there are no supported devices. Has anyone encountered this?

Your LaCie enclosure probably does not support sending the commands needed for flashing to the drive. I guess the only way to get around this is to remove the drive from the enclosure and attach directly it to an IDE channel.
