Posted the following to another thread but no responses, so I thought I'd start a new thread to see if anyone else is having this problem and a potential solution. I'm kicking this topic up to see if any other solutions are known to this problem. I've searched the forum but have not been successful in finding a definitive solution. I also am getting the "E00040003: Error writing the file" message when trying to image my system partition from within Windows. I am able to successfully image the partition from the live boot CD but not from within Windows. I've contacted customer support and received some suggestions, none of which worked. I have a pending response from customer support, so I'll see what that suggests when it arrives. Just thought I'd chech here in case anyone else has resolved this problem. Noticed that one post suggested this is caused by having large system cache enabled in the registry, but that's not my problem. I also uninstalled TI10 and re-installed multiple times to no avail. Running TI10 with Windows XP SP2 and imaging on an external 1394b drive.
