I've used partimage for just this... One downside. It creates "images" that are the same size as the original partition. So it operates on MB not on %. What would be nice is if there was a way to resize a file "image" not just a file system. (ie pull the image to a holding area resize the image, put it on the new drive with the newer larger/smaller size.) Years ago a guy at our then office wrote a program that did disk to disk copy and did it by percentage So that say on a 100mb drive / was 50% of a drive or 50MB, on a new 200mb drive / would become 50% of the new drive or 100MB. I've been trying for the last year to convince him to port it to Linux (from FreeBSD) but ... to no avail (so far). James > > Anybody here having enough C-Knowledge to do that ?
