This is a typical effect of checkreading while writing. 1.0x with 2x nominal speed indicates a good relationship between drive and medium. 0.2x is rather bad. Checkreading is normally done if the BD-R is formatted. growisofs does not offer to disable checkreading, but it offers to leave out automatic formatting of unused BD-R if you add option: -use-the-force-luke=spare=none This will also increase the media capacity to 12219392 blocks. You should of course checkread the resulting medium by own means. ("should" meant as obtrusive advise) Have a nice day :) Thomas
