MacBook Pro started giving me grey screen, no progress bar, no chime, then shutting down. Tried everything I could think of and finally got chimes and option to start from recognized startup hd. But still shut down. I started from DVD and ran disk repair, but got too many errors and could not fix. Started from DVD and only other option is to install, but message says cannot install in current HD - to save all data, reformat and re-install. Problem is I can't figure out how to save any data. Is my only solution to remove HD and replace. Still need way to recover old data. Are there some connectors to get at the old drive once it is out? Any ideas or help appreciated. BTW is it a major pain to change HD? Sure would be nice if Apple didn't make it necessary to remove a million screws (some with very tiny star head patterns). I feel like a watchmaker trying to do anything - even upgrade RAM chips.
