Any advantage to using Erase.. vs Smart..?
I am assuming that after doing several incremental updates to my system and third-party software that the files needed for each application tend to get scattered around my hard drive.
I assume that doing multiple Smart Updates with SuperDuper! probably also fragments files that might better be kept together - yes? no? Does SuperDuper! do any organization or optimization of files when making a clone? Would making a clone using <Erase, Then Copy> have any advantage over <Smart Update> in preventing file fragmentation? -gw |

Yes, a Smart Updated volume, like any active drive, will fragment. An erase-then-copy will defragment the files... but does it really matter?

I'm using Smart Update to clone Drive A to Drive B, then B back to A, A back to B, etc. My concern is this: Is there any cumulative effect of updating a clone of an updated clone? That is, would there be any practical advantage to periodically using Erase, Then Copy? I acknowledge the answer to the following question may not have any real-world significance, but just to be sure I understand how this works: Are you saying Erase, Then Clone actually defragments files, whatever the cause of that fragmentation may have been - as opposed to merely avoiding any fragmentation that may have resulted from doing a Smart Update? |

So you understand WHY I do this, A is my main Mac, B is my external HD and C is my vacation home Mac. YMMV. |

That's right: an erase then copy defragments the files (not the directory structure), regardless of how it got that way.
