Just put together an external hard drive. Peguin case with USB/1394 connections and a WD 330GB ATA drive. When I plug it into either of the 2 USB connections on the front of the case (Antec Sonata), the computer freezes. Have to use the reset button to restart. I plugged my mouse into the same connectors and the mouse works fine. The drive works when I plug the 1384 in the front 1394 connection. The drive also works fine when I use the rear USB connectors. Also works fine on a second computer uisng the USB connection. Any ideas? Thanks
