I'm not lazy this was my third drive from different manufactures that i have been testing to see if will work as advertised. It failed like the others miserably. I have been scouring the forms to find out what is the worst problems people are encountering in scanning and burning CDs and DVDs using clone, clone2, ANYdvd and DVD fab, and using the problems for my testing. This is allot of time consuming testing but well Worth it because I'm finding that one drive can do
My feeling on the ND-3550 A possible production problems or design i have been able to duplicate all the random problems that you can read about in this NEC form
It's possible that the lens was cloudy because my gutfeeling was that the lens was accidentally hitting the disc not a real measurable amount but after several runs with the same new disc speed demonised on several new RW I brought the speed backup with a new ones.
Bonus the discs that 3550A slightly crippled are working full speed on DRU-820A
With all this testing i can now tell from the sound when a drive is struggling with it's task to failure.
My journey is almost over and i have two sweet candidates Sony DRU-820A and the BenQ DW1655
The only problem I'm having is i wanted the BenQ DW1655 with solid burn technology to win so far it's not so solid.
I can use the most expensive and the cheepest media on the market with 820A
people say the 820 is not fast it is deceiving because it's vary quiet and spins slower once you compair it against ND-3550A, DW1655,DRW-1608P2, DUW1616L, fist thing i said was wow
Amazingly the DRU-820a is pulling ahead in allot of real world categories 3-4 more days of rigours testing i hope i have winner.
