I recently bought the 750GB Freeagent Pro for my MacBook Pro. I partitioned it into 200GB for Time machine and the rest for general. Time machine has been working fine until recently. The backups started stalling mid backup, and then the entire computer would start hanging - all apps would be "un-force-quitable." This caused me to have to make 3 or 4 shut downs via holding the power button in. Now, whenever I connect the external hard drive, it shuts off. I turn it on, connect it to the computer ---> shuts off. I turn it off, connect it to the computer, turns on for a second ---> shuts off. I turn it back on while it's still connected to the computer after it shuts off, it turns on for a second ---> shuts off. Hopefully you get the picture. Anyway, anything I can or should do to help my situation? Thanks.
