A demonstration of how to change the hard drive on your mac book.
If you havnt got a new hard drive yet what you need is a 2.5" SATA hard drive. Anyone will do, its worth knowing this as you will probably get charged more for one with 'MacBook' specificity in the title.
Step 1: Taking out the Battery
The hard drive as well as the RAM memory are located behind the battery on your MacBook. Flip your baby over and use a penny to turn the lock, then take your battery out.
Step 2: Getting to it
There's not much to say here unscrew the three little screws and pull the L shaped bit of metal out.
Step 3: Taking the Hard Drive out
See the white tab bit, extend it and yank the hard drive out.
Step 4: Putting the hard drive in
Unscrew the shiny metal with the plastic bit on screw it ontop of your new hard drive. Put in the new hard drive in and work backwards until your MacBook is compleate again.
Sorry for being sparing with the words but its fairly simple to do if you follow the pictures. Hope this was useful to someone :D
