View Full Version : External HD Crashing Mac via USB not Firewire

13th November 2009, 08:22 PM

I have a 250GB External HD and I have installed Leopard on it. However when I mount the HardDrive it only shows up when you connect it via Firewire. If I connect it via USB and use an external power source it force shuts down the whole mac and I have to turn on my mac again. Any idea on why it's doing this and if there is a solution?

Is it a pre-boxed drive from, say, Seagate? Or is it a box-and-drive you bolted together yourself? What brand(s) are the case and HD?
