chef, are you reading my whole posts? I said I patched it with 1Y6, isn't that the firmware update? I think that's the latest firmware for it. When I say loud I mean it makes a jet engine like sound (ok not really a jet engine but you get the idea) when I put in a data cd, or a blank dvd+rw, or when I'm burning on to the dvd+rw with Nero 7. In my test it managed to shut up while burning after reaching like 10%.
I may be a little more sensitive to the noise factor here than most people because recently I decided to make my LOUD computer quiet. It made a lot of noise so I decided to replace all the noisy fans inside with good quiet ones. So now you can barely tell it's on except for my 2 hard drives that make some noise. Still I must say the 3550 is pretty noisy compared to my old NEC 2550 which didn't make any noise and my regular dvd drive which also doesn't make any noise.
