Color me potentially confused...sorry if I'm being dense.

1. It seems to me that if I want to clone a physical volume to a physical volume AND I wish to have a compressed, read-only disk image of the source volume, then I go to the SD Options-->Advanced tab and click the "Image" box, yes?

2. If I want to end up with ONLY a compressed, read-only disk image of the source (and I don't need a clone on a physical volume), then I just need to select "Disk image" in the target drop down on the main SD window.


As far as Disk Utility "Convert" vs SD, I understand that Disk Utility will do a block by block copy whereas SD will do a file by file copy (at least I think I understand this).

BUT, why do I as an end user care which method (block by block vs file by file) gets used? Don't I end up with a compressed, read-only DMG file either way, and the two DMG files are identical in functionality, right?

Again, thanks for your responsiveness and sorry I'm being stupid here.
