Hi all, So I'm finally replacing my PowerBook with a new base model 13" MBP. I've ordered a 640gb Samsung Spinpoint hd to replace the 250 gb stock hd. I've also purchased a Rosewill external to put the stock hd into (all this for less than Apple would have charged to upgrade to a 500gb hd!). Here's the issue: what's the best way to swap hard drives? 1) Put the new one in, and use the recovery discs to install the OS; or 2) Put the new one in the enclosure, clone the hard drive in the mpb, then swap them; or 3) Something else. Any advice you have would be greatly appreciated!
