(Ghost 15 Version 15.0.1.36526) In addition to the USB3.0 problems (SRD works fine using USB2.0 ports), I note that the Recovery Points do not show up in the Tools --> Manage Backup Destination. The status correctly shows the recovery points but nothing shows up in Tools --> Manage Backup Desitnation --> Recovery Point Sets display. Plugging the backup USB 3.0 drive into a USB 2.0 port does nothing either. When I manually delete the task and the data on the backup drive, Ghost still remembers the old backup and will later ask if you want to remove the history of the old backup recovery point. At times I like to start fresh by deleting the old backup data and thus currently I can't easily do this in Ghost 15.
Off topic - Since the USB 3.0 backups run in 8 minutes whereas it took about 2 hours using USB 2.0 drives, sure wish Norton would add the necessary drivers to the Ghost 15 SRD (recovery disk creation). I really hate having to go back to USB 2.0
