Hello, Please bear with this brief preface- A friend has True Image 9.0 and said it works great for him. I noticed 9.0 for sale on the internet very cheap - after reading the forum, I realize this is not a good idea, and will purchase 11.0 from Acronis However- I downloaded a 9.0 trial version just to verify TI would work. I created a rescue disk, and I backed up my hard drive to an external USB drive (Seagate Free Agent 250 Gig). Using max compression, the backup archieve was created ( 15 Gig). When I choose the 'validate back up archieve' option, I get the message "This not the last created volume of the backup archive. Please insert the last created volume to start working with this archive. " I'm unclear as to what's gone wrong. ( I chose 'validate backup archieve' from the main screen of TI - no reboot or restoration disk involved). Since I've decide to go with 11.0, I suppose I'll download the 11.0 demo and try again. One thing that I should mention. I'm having trouble with my virus scan and the 'System Volume Information\tracking.log' file, as my virus scan hangs up there. I'm determining what I should do about this, but I wonder if it's anyway related. I tried to do another backup last night, over night, and this morning the computer was locked up without completing. Maybe coincidence.... Any advice is appreciated, Thanks.
