You would need to replace the bridge board inside the firewire enclosure with an ATA6 capable card . . . If LaCie makes one for your enclosure. Contact them and ask.

Hi Folks, I've added a number of firewire drives to my G4s. I just ran into an odd problem. I just pulled the drive from a laCie Firewire 40GB package and installed a 250GB ATA Maxtor. My problem, I hit the 137GB barrier. Is there any way to change how a firewire(400) reads an external drive to overcome this? TIA -- Steve Jensen Photo Dynamik
