I use a separate hard drive to backup (duplicate) my system on system on a weekly basis. After the duplication has occurred, all desktop icons are duplicated, with one set pointing to one hard drive and the other pointing to the backup drive. This will also occur if I elect to boot up from the back up drive. I don't recall this being a problem in the past and frankly, the novelty is wearing off. Does anyone know how to stop this annoying feature?
