"E66 Explained: DVD model/version Check - E71 Issue Fixed? *Updated*
>> Well we got a bit more details, courtesy Commodore4eva, about the Error 66 some users with modified DVD firmwares got after the Fall 2006 Xbox360 Update.

It looks like Microsoft has implemented 'DVD DEVICE' and 'DVD VERSION' control in the new kernel, a bit similar to the Windows XP/VISTA device upgrade check!
Apparently Microsoft stores the original stock factory drive/version somewhere on the 360, and with the new Fall06 kernel it will give the user an E66 if it detects a drive model or firmware version change.
Update1: it's possible that the hardware info has been stored on the 360 at a later time, like during a previous update, rather than stored from the beginning/factory.
Update2: Apparently MS has been storing drive info on consoles manufactured starting around end of May/begin of June 2006. Consoles made before that date will probably work with any drive model/version. Updated all news below with this new info.

What this means for Toshiba-Samsung TS-H943 drives (in consoles made after ~ end may 2006) is that if the drive was originally loaded with the MS25 firmware (often referred to as an 'MS25 drive') it should work fine with C4E Xtreme v3.3 (based on MS25), but not with C4E Xtreme v4.2 (based on MS28) as that's a version change. On a drive originally loaded with the MS28 firmware (often referred to as an 'MS28 drive') anything below C4E Xtreme v4.0 will not work as v3.3 and below are based on MS25.

It's unclear what Microsoft really tried to achieve here. Maybe they tried to lock out users with modified Toshiba-Samsung TS-H943 MS28 drives. When MS wrote the fall update, C4E Xtreme v4.0+ (which is based on firmware MS28) was probably not released yet and C4E Xtreme v3.3 and lower would be no option for these users as those are based on MS25 ... which is a version change and would thus result in E66.

Hitachi-LG GDR-3120L drives not affected? Well, modified firmwares for the Hitachi-LG don't reflash the whole firmware. Instead they patch small parts of your onboard DVD firmware which will obviously not change the version. Model and version don't changed, so you get no E66.
Exception here could probably be if you use a full flash replacement firmware modchip or if you manually removed the flashchip and flashed it with a different firmware version. I have no real data on this (few people do that), let us know if you fall into this category.

Replacement drives? That's something else we should talk about as it's now probably no longer possible to swap from a Hitachi-LG GDR-3120L to Toshiba-Samsung TS-H943 (or the other way around) as the model of your drive would no longer match the model stored on your 360.
Also, the FW version on your replacement drive should not be different than your stock/factory drive. I suggest you get a drive with the same version as your stock/factory drive if you ever need a replacement drive. Quick note for the new people here: if you ever plan to replace your drive yourself, keep in mind you also have to patch/flash it with your unique DVD drive key - the key-check is of course still there
I wonder if Microsoft did change the DVD model/version info stored on all repaired/refurbished Xbox360s when they swapped a DVD-drive or motherboard ... Let us know if this happened to you

I also have an update about the 'new/refurbished/replaced Xbox360 Error 71 issue' I talked about earlier today (which is totally unrelated to E66 or DVD firmware issues). According to Major Nelson Microsoft released the 'fix' to the Fall 2006 update:
Now ... Microsoft does not want to tell what they fixed exactly. But as E66 is probably on purpose and not a 'problem' for MS, and Major Nelson mentions new/refurbished consoles I'm gonna assume they fixed the E71 issue. Sadly if you already tried to update your brand new system before and got an E71, it looks like you're up for a(nother) swap/repair even before you could play your console for a second.

Damn. That's sneaky. Now another potential reason for the RODs.

It's nothin to worried about if u r not using a flash / mod 360.

Seems MS ady launch their search n destroy device..

Well, that's what we like to think but as my friend's story in the ROD thread goes - non modded also vulnerable. His wass workign fine till he did the fall update...then it hanged, hanged, and then...boom!

Err66 can be fixed. I'm guessing here that your box is modded and you're having a Samsung drive. This problem occurs with these 2 situations :-

1. The Samsung original firmware was using ms25 firmware version and the drive had been flashed with Xtreme4.0 firmware which use ms28 based firmware. The Fall/Jan Update is expecting ms25 drive but instead it detected ms28 so that it gives you ERR66.

2. The Samsung original firmware was using ms28 firmware version and the drive had been flashed with Xtreme3.3 firmware which use ms25 based firmware. The Fall/Jan update is expecting ms28 drive but instead it detected ms25 so that it gives you ERR66.

Also ERR66 can occur for this situation :-
3.If your dvd rom drive originally was a Hitachi drive and you changed it to a Samsung drive, when you do the Fall/Jan update it expecting Hitachi to be reported but instead it got Samsung drive being reported.

How to solve the problem? Simply flash it back to the original firmware or use the latest Xtreme5.2 hacked firmware if you don't have the original firmware.

If you want to flash back to the original firmware, just search for original ms25 or ms28 firmware and use your dvd drive key to patch to the original firmware and flash it back to your drive.

To solve the situation 3 problem. Just use the latest Xtreme5.2 hacked firmware for Samsung and spoof the drive to be Hitachi drive. This means you're using a Samsung drive but it'll report as a Hitachi drive.

tot31. Recommended technical friend for ur lovely 360

Darth Sidious: "Execute Order 66!"

That's why most of the shops that sells modded X360 will say to their customer not to go online as they know this kind of thing will happen. Most of the people that sent to me their modded X360 to be reflashed were having the outdated Xtreme3.3 firmware with Samsung drive. If you're having the Hitachi drive on the other hand this ERR66 will never happens as it always report as Hitachi.

These are the strings inside the dvdrom firmware that are being checked and must be reported accordingly to the drives itselves.

For Hitachi:-
HL-DT-STDVD-ROM GDR3120L0046
HL-DT-STDVD-ROM GDR3120L0047
HL-DT-STDVD-ROM GDR3120L0058
HL-DT-STDVD-ROM GDR3120L0059
HL-DT-STDVD-ROM GDR3120L0078

For Samsung :-
TSSTcorpDVD-ROM TS-H943Ams25
TSSTcorpDVD-ROM TS-H943Ams28

Is this why hitachi does not require a media and fw stealth function no ?? Becoz it does not flash the actual fw and alwaz report as ori fw. Lol..im answering myself

but other with flash firmware are ok with the update,unmodded also have this kind of bircked after this new updates. MS is being sued of this update issues at US.

the unmodded can also get 3rod, if something happen during the update....it's not microsoft fault alone....dude

Whatever it is, to have a piece of mind to play online..just go unmodded, sooner or later microsoft will find out too...as what had happened to teh first xbox....

Others X360 that are not affected with this update is because the string being reported matched with what being requested by the update. For instance if an original Samsung drive is using ms25 and being flashed with Xtreme3.3 the update will success as it is the string is the same that is "TSSTcorpDVD-ROM TS-H943Ams25". Same goes to a Samsung drive that have originally ms28 firmware that being flashed with Xtreme4.0 and above will report the same string i.e "TSSTcorpDVD-ROM TS-H943Ams28". So there will be no ERR66 for them. I've tested this to confirm as my Samsung drive is originally flashed with ms28 and when I flashed it with Xtreme3.3, I got ERR66 and when I flashed to Xtreme5.2, the ERR66 gone.

The initial release of FALL(Nov 06) update had a bug that's why it affected unmodded machines as well and MS has fixed this a couple of days later. The ERR66 is in fact related to modded machines as they're being flashed with the wrong hacked firmwares. If LIVE is your LIFE than stay with unmodded machine.

thank fo your help man .

i don't have that kind of income to by ori games to go online,what i have are 2k of income,one wife and two kid feed,one mom and dad to give them some money,one car loan rm770 to pay and the love to play games
