I ran a full image backup successfully. I then immediately tried to check the image. The image did not verify, I was told it was corrupt. The verify failed in the first half of the checking somewhere. I then closed Acronis, did NOT re-boot and immediately opened Acronis TI8 again. I then did another check of the image. This time the image verified. Now, I ask, do I or do I not have a valid image? Am I supposed to have confidence in this procedure? The external 300GB hard drive is new within the last few days. The notebook is new within the last month. I have used the external disk to backup my desktop 240GB using Dantz Retrospective with no problems (it does a compare also). The notebook has on 80GB drive and I am using Acronis TI8. Is there a real need to exit Acronis before doing a Check Image?
