I recently installed the Seagate Momentus XT 750 into my early 2011 MBP. I used Super Duper to clone my old drive. After installing the new HDD into my MBP it was able to boot up fine. However every so often, on average about an hour apart, my screen flashes and all my currently opened programs are closed. It almost seems like I was logged out and logged back in or something... The model drive I'm using is ST750LX003, I have not installed any firmware updates yet and am having trouble finding any for that model number. Any help would be greatly appreciated.
