Liteon iHAS324 B , riplock 3 second trick not working 100% of the time

hi members , i am doing some DVD ripping and discovered on my other PC that the DVD Drives have riplock. The models are Liteon iHAS324 B , i can hit around 6MB/s. I did some googling and found if i hold the eject button for 3 seconds riplock is disabled and i can hit around 12-15MB/s.

problem is it only lasts once and riplock seems to re-enable , i try the eject button method but it only works about 30% of the time. Anyone knows what i can do or tips to get riplock disabled 100% of the time?. Maybe i’m just not doing it right.
