ok swap th whole drives but switch the dvd motherboards so you keep the original one in the working 360

the green board is the motherboard and has the firmware on it.. but since it is staying on the working xbox you dont need to flash unless you want to play backups

no u misunderstand what i am saying....keep the working dvd motherboard to the working xbox.. just switch the whole rest of the dvd drive out

ok i see... well getting someone to remove firmware chips could be your only option.that or try exactly what i said before cause you still have no real proof that dvd motherboard is bad...cause you stated it would eject and stuff with it taken apart..you wont have modded firmware but it still might work normal

You don't have to "spoof" anything since the drives are the same versions and makes. You do need the key from the old drive though and since you can't get it into modeB then you have a problem.

All of this seems pretty pointless since you should have a backup, or three, of the old drives FW from when you flashed it in the first place, so just get the key from it and patch the new drive, done deal.

If you don't have a backup of your old drives FW then first off shame on ya, but then try swapping the entire DVD drives logic board first as pimpmaul69 has already suggested. If you give the old drives problem to the new drive you'll know you have an issue on the old drives board and it's not something else. Then you're only other option is to swap the flashroms from the boards so the key gets onto the working drive.

You may need to swap the laser and or motor now as well, I just reread your OP and saw that the other drive was broken. It may have a stuck motor or bad laser, so while swapping boards would get it to work in your 360, either of those problems are still going to leave ya with a bad drive.

Take it back apart and spin the motor, see if it feels like it's dragging. If you can hear the disc spinning this isn't the problem.

If the disc spins swap the lasers on them and see what that does.

adendum: and you can still have a bad laser if it doesnt spin when you put a disc in cause a laser controls the speed of the motor

The laser does not "control" the speed of the motor and even if the laser was bad the motor would still spin the disc for a few revolutions after the the disc is insterted. However if the motor is dragging, like the Hitachi likes to do, then you wont get that initial spin at all.

sorry i worded that a little wrong but yes the laser does in fact control the spinning of a motor... i could prove this all day long.adjusting a laser changes how it reads and if it is harder to read it will spin slower and even not spin at all...it controls it only up to the maximmum rpm that the motor will spin but will tell the motor wether to slow down or speed up...otherwise all drive motors would spin at one speed and they dont..

Jacking different value components into the correct places around the driver IC or having a dirty disc will do the same thing, so that line of "proving" it is incorrect, it's only an observation. Unplugging the laser will also result in the same behavior as a coverd up one, the motor does not go full tilt, nor does it not spin at all, there is still the inital "bump" of it after it's tried to sense the disc, so the motor can and will still spin reguardless of the lasers condition. The max RPM of the motor is much higher than what it's run at constantly or at it's max read speed as well, the drive doesn't spin it that fast because there's no need to, so that's incorrect also.

That's why "control" was quoted in my previous post. The motor driver IC is still what varies the speed, not the laser itself, but varies it according to the data it's given (from the laser), so you're still only halfway there.

Old LD players do spin the drive motor at one speed, CAV.

i would be scared as hell to see one of my laserdiscs spin at a different speed... would you wanna open that drive if it was retarded and was spinning hella fast while you opened it.. also any old 1x laser is the same but if someone still uses one of them drives then...damn...

did you boot the 3rol box without the dvd drive to see if maybe that was the problem?

pimpmaul69 · « **Reply #12 on:** March 19, 2007, 09:34:00 PM »

there are people here who can swap the 2 firmware chips for a fee..

Thank you again for all your responses! You guys are great here.

RDC said he would be willing to take a look at the drive if i still cant get anywhere.. i am trying my friends X360 USB - Sata kit tomorrow to see if that helps..

If not, off to RDC it goes... and i didnt even think that you could just swap the drives... hmm great idea

Thanks again
