A friend has installed V9 on their PC on my recommendation. The backup drive is an IDE drive using a USB 2 portable enclosure. I have tried the disk on my machine with no problems and it will accept copied files fine on my friends computer. The first time True Image started to run backup ok but halted partway through. We were backing up two partitions and one was a Fat32. I wondered if that could have stopped it so deleted the backup file and tried again just with the NTFS partition but since then it just sits on 0% despite uninstalling and re-installing. It did not ask for the Serial Number when re-installing which is strange. My friend is running Norton Security. Could this be a problem? Any other ideas?
