    Hey everyone,

    Has anyone else experienced this?

    When I'm not plugged into AC -- I get random 'Device Removal' errors, wherein my external drives unmount and mount.

    This specifically happens when my computer goes into sleep [screen black mode] or when the monitor dims and comes back on. It's very strange.

    Are all the USB ports on the Macbook Pro 17" [late 08 version] have the same power/capability?

    It's really confusing...

    Thanks! MD
