[Clonezilla-live] clone usb drive on disk partition

[stefano p. <th...@gm...>]

I all, I come from an hard debian intallation on external usb hard disk, and
I wanna clone the usb disk content to avoid redoing further installation...
On my locale hd I have windows vista , partitions hda0 (SO)  and
hda1(recovery), while on my usb hd I have lenny in partition sdb1 and
sdb5(swap).
I have read the sample from the site but there are some things not clears
and that  I would understand before committing mistakes.
1. Can I clone the Usb drive? (in the example only locale drive are
mentioned)
2. Can I save the clone image in  vista partition (hda0)? If so, can I be
sure windows data are not overwritten?
thanks all
