Greetings. I installed a new hard drive in my MacBook Pro 17" Late 2008 about 3 months ago. It is running OSX Lion and has been functioning fine. I tried to boot up and got the flashing file folder on the center of the screen this morning. I have figured out it is the hard drive and not a cable issue. Fortunately, I used a cloning program when I switched hard drives and I removed the old drive and stored it away. I was able to boot the machine via the old drive and usb case. Is it possible to recover my old emails and folders that I had in Thunderbird 12.0? I am able to access the internal drive even though it will not function as the boot drive. I'm dying here!!! Any suggestions?
