Disk Fragmentation
Very pleased with SuperDuper which I have used for a few weeks to clone back up my HD internal drive(363 GB of which just over 130GB is in use) to a new Lacie external drive(500 GB). I started with the full clone and then used Smart updates.
I also use TechtoolPro for maintenance and noticed that my recently defragmented internal drive has 2198 disk fragments compared to the cloned external drive of 5486. The figures for fragmented files went the other way-76 for HD and 34 for Lacie; file fragments 678 for HD and 247 for Lacie. Perhaps the latter is as a result of not cloning all files-the ones Apple suggests you do not according to SD.
Two questions please:1) Why the difference in disk fragements? and 2) What are these files that are not copied over?
