Hi Mencorman I made a new back up last night - ticked the VALIDATE IMAGE box in the settings sections and it all ran through fine. I even loaded the image fine by browsing to the HD where they were stored and got the point where I was ready to proceed with restore. However burnt to a dvd - same thing as soon as I select the (or one of) archive files IMAGE IS NOT A TRUE IMAGE FILE OR IS CORRUPTED. I have also burnt on a different PC with a different version of nero. Using version 10 is too easy at work we only have version 9. One thing I noticed today. I took a 650 mb split of a laptop for a test. It said there was like 28 mins left - it seemed it was creating a new volume then it went up to 2 hours started dropping down then suddenly zapped a few green lines across and then said completed successfully - I checked the file sizes and they were ok though - wierd?
