I have an external LaCie drive connected to my eMac and it has always worked fine. Now, I have got another external LaCie drive, but I can not get it to mount on my desktop. In know the cables are good, and it starts up when I start my Mac, but nothing comes up on my desktop. It has been formated on another Mac. Is there any thing I can try to get it to mount on my desktop? As I dont have Firewire 800 on my Mac, can I connect it to my other Firewire drive with the Firewire 800 cable?
