I uses Acronis True Image 8 for windows. I make Images all the time. I place the images on an other computer and connection to that computer by a switch. I make many Images of different computer. I have computers go out all the time. About after a week when restoreing a image I get an error saying my image is corrupted. I have made all levels of images, and for many different computer. Now all the images are bad. I save them on a computer running Windows XP, P3 and 160ga hard drive. I have run many Virus Scans and Adware and spyware scan and have found nothing in the scans. I do not use defragmentor on this computer, so my files are not put out of place. I uses to do this and found the same problem so I stop(I thought that was the problem). This is a very clean computer. Need help to find out why this is happen.
