Urgent: Copy hda to hdb with dd?

[Bill Warner]

I have done this many times, although not in quite some time.  there
should not have been any trouble with it messing up the first drive at
all.  You also should not have it mounted when you do it or it will boot
fist time and say it is an unclean system and run fsck.

I saw in a hack Tivo site that someone hacked a progress meter into dd
because this was one of the only ways to backup the tivo hard drives
when they first started hacking them.

it does take along time.  one suggestin I would have is put them on
sperate busses hda->hdb not the best hda->hdc would be much better and
about twice as fast.

if you fear causeing issues with destroying your primary drive then log
in as root with your boot disk and make a user.  make sure the user only
has read access to hda and give him full access to hdc.

hope this helps some
