My OSX crashed and so i decided it was time to upgrade my macbook harddrive and install Leopard. Everything went fine. I could read my data on the old drive in an external OWC case. I had to wait to install iTunes. I just got it installed, and now the external old harddrive is not working. It is a toshiba 80gb that now sounds like its trying to read but then clicks, sounds like the ball in a spray paint can. It does this for a while then goes back to smooth but will not load into OSX, doesn't even show up in disk utility. Any ideas? Thanks guys! The data recovery guys are saying it will be $695 to recover!
