2.2Ghz 15" MBP, and I need to swap hard drives. I'm swapping my Seagate Momentus XT (SD25) which has all of my data on it, to the Mac. I also want to transfer all of my data along with the hard drive. There's two options: 1. Move all of my data to an external drive via USB/ethernet, swap hard drives, install OS X and move the files back 2. Swap hard drives first, install Mac on unallocated space, and move data via local file transfer Theoretically the first one should take 3 days to complete. The second one should take 3 hours or less. The problem is, I don't know if the second option will work. I'm also confused on OS X's compatibility with NTFS. Are NTFS file partitions read-only in OS X, or do they not show up at all? Are any of these viable solutions, or do you have any other suggestions? Thanks!
