I have two identical 1G ide drives, wd0, wd1. I want to back up all of wd0 to wd1 periodically, say nightly. When I tried: dd if=/dev/rdw0c of=/dev/rdw1c bs=some chunks here I was told: dd: /dev/rwd1c: Read-only file system Why is this and what might be the best way of doing this anyway? I want wd1 to end up as a clone of wd0 in case of a crash. regards, Jim Binkley jrb@cs.pdx.edu
