I agree with Alberto's description of the issue -- I've seen the same behavior with my 500G FreeAgent.
i.e., the issue happens after the drive shuts off, and then at that point, any access seems to cause problems.
Also, JrFrost's solution has still been working for me. (although I need to repeat it on every reboot and whenever I disconnect and reconnect a FreeAgent drive)
