It's a bit uncomfortable. Just for example: I need to search some
signatures, which could be anywhere in 640Gb disk, and make some
changes around them. And I don't have spare 640+ Gb to copy whole disk
to. And even if I would have enough space, it is painfully slow to
move 640Gb twice just to make ten minutes editing.
