Okay, so I know this will make me look like an idiot, ( I honestly don't know why the crap I did it, you know when you just do something and don't think first. Well this is what happened) Okay, So I got a new 500gb HD for my macbook 2008 uni and I installed SnowL on it and it all works like a charm. However, me being an idiot decided it was a good idea to open my Lacie EXT hd and plug my original macbook hd into the cables there and try to read them on my macbook. Everything plugged in perfectly, turned it on and.... nothing happened. Tried a few more times, then decided to swap it into my macbook and load up. Well, that didn't work. My macbook can't find the original HD now. It doesn't even startup. So yeah. My Question is, is the HD hooped? Is there some little trick to kick start it again?
