I have been running Acronis True Image for more than a year and for the last six months on my Vista machine. I was backing up my raid drives to an external 'My Book' drive via firewire. That all changed yesterday when I added another SATA drive to my system. The computer recognizes the drive and so does Acronis. But when I try to do a backup, the event completes immediately with: Operation has completed with errors. I have tried the backup to the 'My Book' external and to the new internal drive with the same results. I disconnected the new internal drive and tried a backup to my 'My Book' external (this used to work) with the same results. I don't know if I am fighting a 'Vista' problem or an Acronis issue. Anyone with a possible solution or process step please respond.
