I have two external USB drives: one for my weekly Ghost 15 backups of my C and D drives, the other a big 2TB storage drive for large/rarely used files. If I try to create a backup of my Ghost backups, it will start then error out with a mesage about not being able to find the file. Anyone know why? Could be something to do with moving a file from one external USB drive to another? Ghost is not running when I try this.
