Thank you for your answer.
I tested it one last time before sending it and it was getting worse, 1m06s.
I got my drive checked at the store (they had to check it first). One week later they called me and gave me an 3520. The technician said it had no loading problems with it, odd. Anyway, my new 3520 works great, i can boot with my dvd+r's now. :bigsmile:
