I've noticed a lot of people are discovering that their images are corrupt when checked with the "Check Archive" fuction in TI9. Sadly I've been getting that error too, ever since I installed TI9. So, I decided to do somthing about it, and fix the (at least my) problem. I found out that making an image with compression level on maximum always results in a corrupt image. Weird huh? So I tried normal, and tadaa it's working! I did 5 backups with maximum compression level which all were corrupted, and 5 with normal compression level which all were fine. If setting compression level to normal does not solve your problem try low or high. I only hope this can help anybody else having this problem and the Acronis team in resolving the issue. I'm using the latest build 2323 of TI9.
