Hi there- Bought a new Unibody 2.54Ghz MBP about 3 months ago. Had a few issues with it and finally got approved my DOA last week. I thought "what the heck" since they're replacing it with a new one anyway, I'll pay the difference and get the 2.8Ghz model instead of a straight swap. All good- the new machine arrived today. Now... I've got my current 2.54Ghz machine running just the way I like it- I want to use Carbon Copy Cloner to clone my current (2.54 unibody) STOCK 320GB drive to a Seagate 320GB I bought a while ago and had my old machine running off. THEN, drop the Seagate 320GB in the brand new unibody 2.8 I just got. (the drive that came with the new 2.8Ghz unibody is a 250GB, I got it to minimise the gap cost I paid, I plan on getting the 500GB 7200rpm Seagate in the next month or so anyway, so, Im not using this). Q's- Will cloning my old drive that was in my 2.54 Uni, and then dropping it in a 2.8 Uni cause any problems? Will putting the 250GB that came with my new Uni 2.8 in an old non uni 07 MBP machine cause any issues? ( I want to sell this with the 250GB) Any help appreciated.
