Here's the way I've been doing it on the Shuttle
(small form factor box, like the one Greg has been
using for his demos). I've been doing rotating
clone-backups, with identical WD 80G drives . . .
though my intention is to switch to Seagate 120G
drives in the near future. There are two separate,
independent IDE controllers / channels in the Shuttle
(I'm not using any Master / Slave configuration, so
that is one less complication to deal with) -- one for
the HDD, one for the DVD.

I have to take the cover off, and disconnect the
optical drive, in order to connect the other HDD. (Of
course, this is borrowing the power AND the data
connector from the optical drive.) That means NO CD
will be available during this procedure. No problem
-- as long as there is a FDD in your box, as there is
in this one, either Partition Magic or DFSEE have FDD
versions. I think it would be better to boot up this
way In Any Case (you need to boot with a DOS boot
disk, before you can run either program), because then
your HDDs are spinning, but neither HDD _belongs_ to
any OS *on* one of them, if you know what I mean.
That is going to give you the maximum freedom, safety,
and room to maneuver.

When the drive to be cloned happens to be a bare
drive, I just clone away, using DFSEE. I use ver.
6.17, because there were menu item changes in the
later 7.x versions that confuse me -- *to me*, the
action descriptions are now looking through "the other
end of the telescope", and I don't need the extra
options now being offered. It is CRITICALLY IMPORTANT
to be sure that one has the SOURCE and TARGET HDDs
correctly designated, so any source of possible
confusion is to be avoided.

When the Target drive is NOT bare, I wipe it with
zeros prior to cloning. Why ? Because I've found
it to be the soundest method. Other boot partitions
(like eCS) may or may not care, but the Win-32 boot
partitions show a definite propensity towards getting
screwed up, or even turning out unbootable, when you
simply overwrite them, leaving ANYTHING there from
before. I do this with the SOURCE drive UNPLUGGED, to
avoid any chance of a mistake. Wiping a good, working
(though not up to date) HDD may seem like a risk, but
remember, I have 3 of these drives in the rotation,
so there is always a more up to date cloned backup
untouched.

In deference to Svobi and Peter, I have done this
many, many times, and haven't screwed up yet. (Knock
wood.)

Trust me, and I know Peter will squawk loudly if I
fail to mention this, but you definitely want to carry
out this operation while running off of a good UPS !

Incidentally, Jan has added USB support to DFSEE. I
guess this means it should be possible not to have to
open the case any more, and to do this over a USB
connection with another HDD in a powered, portable
"drive shell" instead. But I haven't attempted this
yet.
