Just bought myself a Travelstar 250gig drive that I want to put into my MBP. Now I have an external drive on USB2, if I put my new drive in this housing, will I be able to clone the existing 160gig drive using CarbonCopyCloner? Through USB2? If I can then I will take out my old drive and put in the new one, and hopefully be able to run my computer as before. Any feedback welcome!
