If you would have read what I wrote before you would have understood
that that is not true. You have as well misunderstood that part of the
readme which is indeed quite unclear.
I myself tested lower speedsettings with the 1.6 FW and can emphasize
that the FW either does not include such a check or the check does not
work.
Anyway, like I already wrote in an earlier posting: The drive is
constructed in a way that it lowers the speed by itself from
12x to 8x to 5x to 2x in 3 steps if necessary. That is a specially denoted
behaviour, which is also described in the XBOX SDK.
Therefor these speeds are expected by the 360 kernel and
applications to occour. Using these speeds does not include any risk
of being banned from LIVE at all, because they are supported and
may happen under normal use.
Recognizing the 360 can - and does - change drive speeds at times, I'd still like to play devil's advocate here and ask another question.
Wouldn't it still be possible for the 360 to attempt to read a disc at 12x speed - and then not be allowed by the drive's f/w (assuming you've changed it to a lower setting when flashing)? From there, couldn't that be logged - the fact that it tried reading at 12x speed but wasn't allowed to do so at all?
Your arguments make sense but, in each situation, the drive speed
always started at 12x and then went down from there if needed. If the system isn't allowed to start at 12x speed, could that cause an issue that's possibly detectable?
Finally, what do you guys know that C4eva and Team HyperX
doesn't know? With *no* disrespect intended - they've been the ones creating the firmware and have had all the right info in the past. If they're telling us that M$ has possibly used drive speed as one of the detection methods in past ban waves, why shouldn't we believe them?
You guys are acting like people are saying M$ will ban you solely for using a non-12x drive speed f/w. Nobody is saying that. However, what they are saying is that they believe drive speed was
one of the many factors used in previous ban waves. How is reducing the number of ways M$ detects people - or eliminating one of them altogether - a bad thing?
The bottom line is - do what you want to do if it makes you happy. But until C4eva and Team HyperX says something different, I'll respectfully choose to listen to them first.
