I had E: as my backup drive. Then I added a new drive F: and my backups now go to that drive. However, Ghost has both E: and F: listed as "backup drives" and gives me errors because there isn't anything backed up to E. How do I convince Ghost that E: is no longer a backup drive? (No option to make any changes in "Manage Backup Drives" because there isn't any backup data on E:. In fact, E: now has "live" data and is part of the backup job to F:)
