Hey everyone .. I have a black MacBook 13", model A1181 I believe .. Well, a while back I dropped a heavy object near the trackpad while the MacBook was on and after that I got the infamous folder with a question mark upon start up. My research led me to believe that I killed my hard drive when I dropped the object on the MacBook. Awesome . So, obviously I need a new hard drive, and I need a fairly common 2.5" Sata HD ... Here's where my question comes in, and I'm just trying to problem solve and thinking critically before purchasing stuff. I have a SeaGate Free Agent GoFlex 640GB external hard drive that I've used to back up docs and pics in the past. I was wondering if it would be possible to disassemble to enclosure where this hard drive is in, and use THIS hard drive to replace the dead hard drive in my MacBook? Question 2 - if this is possible, I will obviously need to download/purchase OS X to put on this hard drive. So, could I download the OS X and simply install it on this external hard drive from another laptop while it is still assembled .. THEN disassemble it, put it in my MacBook, and it start up good as new? Question 3 - what about the documents and pics I've previously saved on here? Will they still be on the hard drive when I insert it into my MacBook and assessable? Ok, I think that about covers all my questions lol, I really really hope you guys can help me out with this, and thanks in advance!
