Anybody experienced this with a new Unibody MBP: Insert a FW800 cable attached to a 500GB lacie drive, and... Ping MBP is off, no shutdown, no crash, just off, instantly... If i do it under battery power it wont start up untill i plug in the power again. It happens when the drive is turned off or on, but not if the FW cable is not attached to the drive at all. Haven't a chance to test it with other drives yet but will. Doesn't seem good.
