I am trying to use Ghost to do automated backups with a USB flash drive. The Flash drive (64mb) is big enough for 3 backups. When I try to do an automated backup for the fourth time, I get the error message: Error ED800016: The target disk is full. (UMI:V-281-3215-607
I have clicked the button that says: "Automatically optimize storage." It still doesn't deleted the old backups. How can I fix this?
