Hey guys, I got a new iMac and I have a problem with my FW400. In system profiler under "Firewire" it says: " FireWire Bus: Maximum Speed: Up to 800 Mb/sec " My Western Digital MyBook Premium doesn't connect via FW400. It's got me quite worried since I've only had it for a couple of days. I've tried resetting PRAM, the SMC wit no avail. Any ideas?
