I highly recommend the shiny-surface version of the Verbatim DataLifePlus disks over these white-coated ones. As far as I know they should be idetical except for that shiny vs. white surface difference, but I have bought at least three 50-pack spindles of the shiny version and have encountered maybe one or two bad disks. My 50-pack of the white ones, on the other hand, had at least 10 bad disks according to two separate DVD-recording devices. I wondered if both my devices happened to be going bad at the same time but since switching back to the shiny version I have yet to encounter another bad disk.
