Hi, I just installed Acronis TI 10 and started to make DVD backups. The operation was to require 3 disks, and all went according to plan until the last disk finished with the error of "poor media quality." Since then, nothing will burn to DVD. WMP, Acronis, iTunes, not even Windows. In fact, Windows can't even format a disk anymore. It says "Windows was unable to complete the format." (Yes, I tried the hotfix.) I've tried looking for driver updates, uninstalling the driver, System Restore, resetting the BIOS - just about everything but a complete reformat. Ironic that a backup program would lead to the loss of all data. Any suggestions? - Peter EDIT: It might be noteworthy that after the Acronis installation, my system went into it's pre-Windows interface and froze at the "loading..." screen. It should also be noted that I have had success (albeit I haven't tried to restore the data) backing up to an external HD.
