I plug-in my backup device that has previously worked fine to backup my computer hard drive. I click on Norton 360 backup and tell it to get busy. Norton 360 responds: "There is a backup problem. Make sure the destination drive or device is connected and then try again." After dozens of attempts, shut-downs, restarts, I get the same response from Norton 360.
How do I fix the error? There is no link to a solution in the error message. Mechanical Nathan tech support has been no help.
