Will it clone a 1 gig to a 2 gig drive? Don't think so. Now, for the longer answers: I've used DD many times for all sorts of cloning and backup schemes. Works great, just be sure you get the right device (/dev/hda, /dev/hda1, etc), and be aware of what you said and what you really meant ;-) For cloning an install, I assume you could use that disk that Mandrake offered to make so you could do just that - clone an install. But I doubt that it would clone any config changes you make AFTER the install. So, if you want to clone a post-installed configuration, the safest thing would be to buy 'n' identical hard drives, to be placed as /dev/hda (or /dev/sda, or whatever) on the target machine, with a second hard drive to be mounted as /whatever which may be different size but does not have any info you want cloned, install and configure one machine, dd-clone the /dev/hda drives, partition and format the /dev/hdb drives, install everything into the cloned machines, reboot, and off you go. I've not tried THIS approach, but it should work just fine. Another option would be to make /boot the identical size on all drives (and starting at the same location!), clone with dd that, and use tar on the rest I've not tried this 3rd approach, it may not work! rusty Rusty Carruth Email: [EMAIL PROTECTED] or [EMAIL PROTECTED] Voice: (480) 345-3621 SnailMail: Schlumberger ATE FAX: (480) 345-8793 7855 S.

Look on freshmeat. There is a prog called partimage that is a Ghost type program. This may do what you want. -Original Message- From: Bug Hunter [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 20, 2000 10:44 AM To: [EMAIL PROTECTED] Subject: [expert] cloning hard drives I have a project in which I need to set up linux (we will be using mandrake) on a machine, and the other identical machines will be cloned from that hard drive.

I used the steps in the guide below. I did partition the new drive so it had the same # of partitions. It gives different ways to clone and problems. For the record I used the second (ii) method. http://www.storm.ca/~yan/Hard-Disk-Upgrade.html Jim Pendley
