You know, sometimes you can analyze till your blue in the face. Just because it is Microsoft, doesn't mean they are above and beyond the bounds of electricity and coding. It is what it is. OBVIOUSLY, if M$ would of been able to simply detect modified firmware and then BAN, THEY WOULD.
Exactly, its not that microsoft can't download and analyze the firmware off the net, its that read/flash the drives (at least the ms28 and the benq), you have to make it go into recovery mode, not something thats an ordinary function of the drive while its being run by the 360.
So basically microsoft tries to detect end results. Anything that happens while the disc is running that wouldn't be an oridinary response from stock firmware with an original disc. Missing/Bad Stealth sectors etc...
One has to wonder how many more tricks they have left up their sleeve with this approach, the last technique they used was the jitter check, but it ended up banning alot of legitimate consoles, because bad dvd drives or scratched discs could create similar results to a modified console.
I'm no technological genious, but as long as the drives require them to be in recovery mode to dump the firmware, it would extremely difficult for microsoft to read the firmware on your console's dvd drive. Therefore they'll have to keep trying to detect the subtle differences in drive/disc responses on drives with modified and non-modified firmware.
