I have a new Vista computer with two internal drives - C: is the main (SATA) drive, the one I want to image and periodically backup. F: is an IDE drive which I will only use for the backups of C: Using ATI 11 (lastest build), every image I create on F: fails verification. I have run the Memtest suggested elsewhere with no problems. I contacted customer service to see about getting a refund, and they sent me a link to update the SNAPI driver, which didn't help either. I have run two different disk checks on F: and found no problems. One thing worth noting is that this drive was just removed from another computer where it was the backup drive using a copy of ATI 8 and worked fine. As a test, I created an image of C: on C: itself. It verified fine. I also tried using an external USB drive, and that image verified OK. All of the chipset and other drivers are up to date. Any ideas as to what could be causing problems with this one drive? Is there some OS setting (write cache, etc) which might fix the issue?
