I recently did my first backup of 50 gigs worth of music with Nero 7. Nero said the process completed successfully. However, in the log, 3 of the 11 disks have a sector or two that does not match the original. Despite that, the log says that the data verification completed successfully...what does this mean? Should I worry about the 5 sectors that don't match in this project? Oh another thing, several of the file names were too long so I chose 8.3 to allow the orig file names to be restored. the log looks something like this sector XXXXX does not match the original data verification completed successfully this project took 5 hours or more so if I don't have to do it again... Help!
