I have an external USB enclosure by ICYDOCK and a Santa Rosa Macbook Pro. The hard drive is a 120 GB Hitachi and is formatted as "Mac OS Extended (Journaled)". When I attach the USB connector to the USB port on the left side, it won't mount. When I attach to the USB port on the right side of the MBP, it mounts and works just fine. Verifying the drive turned up no issues. I've also used a Wacom tablet on the left side and had no issues. I don't remember using anything else on that left USB port. Anyone know what might be wrong or something I can do to try and fix this? It's not a huge deal at the moment, but I would like to be able to use both USB ports to their full potential. Any help is appreciated. Thank you.
