Windows XP SP2, TrueImage 9.0.2337 I regularly make image backups of my system partition (C) to a USB external drive. I specify these images be split at 4.3 GB so I can later copy them to DVD. The total image size is about 6 GB so I end up with two parts. I have been doing this from within Windows, using a TI scheduled task that I invoke manually. Note that I never do an incremental backup; each time I choose to overrite the previous full backup. I have been doing this without any problem for some months now. Recently I decided it might be better practice to perform this operation from the rescue CD rather than from within Windows. I performed the first backup into an empty folder on my target drive without problem. When I went to make the second backup using the rescue CD, choosing a full, split backup which would overwrite the first one, I received the error "Error opening file", and the options to Retry or Cancel. Retry repeated the error, so I chose Cancel, and was returned to the Operations menu. I then chose to repeat the same task: full image backup, split at 4.3 GB. This time I was given a message that the archive was corrupted or not a TI image file, and the option to continue and overwrite it. This I chose to do, and the operation succeeded. As far as I can tell the resulting image is fine; it verifies, I can plug it, etc. Please note this error only happens if the image is split; I can perform repeated full backups using the rescue CD to an image that is not split and I do not get the "Error opening file" message. I can also perform repeated full backups to a split image under Windows without any error. This problem occurs at least with builds 2323 and 2337; I have not tried earlier builds.
