DVD drive/burner is a TSSTcorp DVD±RW SU-208CB SCSI CDrom device.
The reach 99% and eject source disc has occurred with numerous different source discs. As I stated, usually cleaning the disc will alleviate the problem although some times a different disc must be copied before the one acting up works. Movies which have been copied when the problem have worked fine when the DVDfab processes 100% of the disc without issue.
I am trying to determine if anyone else is having this problem because then it would be a software issue. If no one else is having a problem with the copy reaching 99% and ejecting then I know it is a hardware issue and I need to replace the drive.
