I've got a couple of computers at work with 40GB HD's. They have a couple of catalog applications on them that have eaten up all the free space. One of the applications is an older version that the vendor won't let me reinstall, because they want me to use the newer version, that I also have, but it sucks. So I want to clone the existing HD and install some larger drives. Any recommendations as far as software to use ? I have a couple of Western Digital HD's that I may use, they ususally come with some software tools, any use ? Things to watch out for ?
