A little advice for taking off the 4 screws on the tray, use pliers to loosen the screws first. When they say there "extremely" tight, there EXTREMELY tight. And they do strip very easy. So get some pliers and loosen the screws first with it then you can remove it with the screw driver.
Other then that, I can't really help you with transferring your data, my only advice is to buy a external HDD, if only I had my 1 TB External HDD when I switched HDD on my PS3, I still would of had 2 very important saves.
