There ya go! Well, some people in the forum have mentioned that using the latest version of nVidia drivers works for them. However, I have no idea which Nforce chipset that applies to. I guess this bit is up to you if you want to spend some more time experimenting with those IDE drivers. If not, it doesn't matter since things are least seem to be working.
Quality issues are the sort of thing a firmware update will deal with. However, if your drive is already using the latest version of firmware (1.02), then there is no point in looking at that. The next thing is to match the drive up with discs that it likes. The 4166B does quite well with a range of 16x media. Have a look at CDFreaks' review of the drive for details on what media it likes :
