Thanks for taking the time, Acronis True Image 11 Home Win XP Pro sp2 120gb IDE (prim) [20% used] / 250gb SATA (slv) [30% used] / 250gb USB WD Passport (ext backup) [empty] Installed software - created bootable media disk - initiated backup wizard - chose "My Computer" - "Disks and Partitions" - C: and D: (ide and sata drives) - exclude nothing - Backup archive location as E:/Full Backup/ (ext usb drive) - Create a full new backup - Proceed - Error! "Unable to initialize snapshot manager library" and "A required privilege is not held by the client". Reboot, try again, same thing, however; when I scheduled a backup to take place two minutes later it seemed to work (copied files for an hour or so). However when I start the program today it warns me that no backup exists, and cannot seem to recognize the thirty 4gb files it created just last night - at least not as its own backup files (although I'm looking right at them). I intend to replace both HDDs (1 SATA and 1 IDE) with 2 new SATA drives, this is my mission. Any tips or hints would be greatly appreciated, Thank you.
