To clarify on his behalf (save taking him away from coding)

Originally he(xbc) was ripping the entire data partition on xbox 1 games, whereas now it just rips the files (by default). On xbox 1, theres no extra data outside the filesystem, so it works fine, and is generally much quicker as very few games fill up the data partition to any extent at all.
Hopefully one day we will work out file based copying on 360 ISOs too, but not just yet, because theres mysterious hidden bits not referenced by the filesystem.
Id note though, you can rip Xbox 1 games without a modified drive if you are making a rip for single layer xtreme 5 firmware, just by hotswapping (because those isos have no embedded stealth or security sectors).
