i tried backing up my copy using alcohol the exact same way and got the exact same results using imation and tdk 48x media.
i also tried the latest version of clone cd and nero and still get the same results.
i even set the read speed to minimum.
i got errors up to 10232 but people say thats normal.
im using liteon 24102b with latest firmware and no programs running while burning.
hope these guys can help us!
