Hi, I just bought a Lacie d2 Quadra hard drive for my system that I intend to use as my time machine backup drive. As I write this it is backing up my whole system via firewire 800 diasy-chained to the G tech firewire 800 drive that I use for Logic. I decided to do some work in Logic while this was going on and I was greeted with serious sound distortion. I changed applications and discovered that the distortion is pretty much system wide. Changing the settings on my apogee control panel has no effect. Can an external hard drive cause this? I bought the Lacie d2 quadra drive because it was supposed to be extremely quiet.
