I did this mod, written 2 discs one with sonic and one with nero 22.214.171.124.
Perfect! (both +Rs at 8x), and it solved a problem i had where the lead in took 58 seconds, it now takes 20! Scans are excellent too.
My drive was previousley 451 @851 GS0C, just updated right away and rebooted.
Take note: The flashing program goes straight to 100%, but if you just leave it there a dialogue comes up saying successful.
