dd will do what you require.

check out this url for some info on dd....

http://www.crazytrain.com/dd.html

or read this email I archived for reference:

    You have a Windoze partition, let's say /dev/hda1, and you're trying 
to dd it
    with: dd if=/dev/hda1 of=win.img, but when you restore it to the HD 
with: dd
    if=win.img of=/dev/hda you can't boot.

    The point here is, like you said, that boot information is recorded 
at the MBR
    and MBR is not acessible through /dev/hda1 MBR is at the first 512 
Bytes of the
    HD, it is only acessible trough /dev/hda (this dev points to the 
whole HD). I
    have done a backup of a whole HD once with dd if=/dev/hda 
of=win.img, notice that
    I copied the whole deal, including its partion table, MBR and so on; 
when I
    restored it, everything was just like it was, partions, boot, 
files.... I've just
    made a linux backup that way but I can't tell if it worked since I 
didn't restore
    it to the original HD. This kind of backup will only work if you're 
putting the
    data back in the HD you fetched the image, or in a HD that's is has 
the same
    properties.


so I would suggest the following will do exactly what your looking for:


assuming:

your first disk is /dev/hda
your second disk to receive the image in primary slave - /dev/hdb

dd if=/dev/hda of=/dev/hdb

this will do the whole drive - but you may have trouble if /dev/hda is 
larger than /dev/hdb
in which case you may need to do partition by partition and then do the 
mbr separatly.

disclaimer:  I have not tried this!!  but have used dd successfully for 
other stuff.

cheers
Mark
