I installed v11 of True Image, I've been using True Image since v9. Went to backup my HD to an external drive connected via USB and the backup failed about a minute into it. Attempted several times to backup, rebooted, cold boot, ect., even uninstalled and reinstalled v11. Still same issue. So, I then uninstalled v11 and reinstalled v10 and everything worked just fine. So I'm looking for any suggestions and here is my setup. Vista x64 with 6GB of memory. Data drive to backup is 1TB, of which 400GB is filled Backup driver is 500GB of which 500GB is free and this drive is attached via USB 2.0 Thanks for any support and assistance.
