Before upgrading to a larger HD, you'll want to "clone" your original HD using the donation-ware program "Carbon Copy Cloner" (http://www.bombich.com/). Put the new HD in an external case; clone the original; test the clone (by starting up with it), then take apart the MacBook to put the new HD in the MacBook, and the original in the external case for use as a backup, etc. (You can't just drag the contents of the original HD to the new HD, and expect it to work; not since the days of OS 9 and before.)
