I'm going to replace my MacBook hard drive and have been reading online instructions but the part I'm concerned about is the removal of the drive bracket (and putting it back onto the new drive) - how do I orient the device onto the bracket? Label-side up or down? Which top/bottom of the drive to put corresponding to the white label bit? Also, what type of screwdriver do I need for the bracket? I understand it's a Philips 0 for the actual RAM bracket but what for the hard-drive bracket? Many thanks!!
