Are you writing to a CD-RW? If so, you need to "blank" it first (however you do that with Easy PC Backup). If using a CD-R, I really don't know what could be wrong. Make sure you're using a CD-R without data already on it. Sorry I can't be more helpful. (I only use CD-RWs, myself, 'though they do wear out after a while.) --- Gail Prime One <http://www.sbcglobal.net/~prime_one> wrote: > Hi Robert, > > Here is the error I get when trying to use Easy PC Backup. > > The backup archive could not be opened on the destination drive if you are > attempting to update a backup archive, or the destination drive is not ready > to accept the writing of the backup.
