I know im a noob  

I found Textbook's guide, and was reading through it.
Seeing that flashing a TS-943 is a completely different procedure, and that I should use Iprep and in DOS not windows.

Im gonna try this out when I get home then, and hopefully get it flashed correctly. Still not sure if it will work though.

If anyone else has any suggestions please let me know.

Hi, please ignore all of the above, cant believe how confused I was only 24 hours ago. Textbook guide really cleared some things up. And after testing and reading everywhere I could find for the whole of yesterday. I finally got my TS-943 flashed, and its working on my 360!  

There is still a problem however...
The drive still wont eject. The box will boot up fine, but when I press eject, the light starts blinking, and it says OPENING. But the drive doesnt even try to open.

I think I may have fried something on the xbox itself when initially doing the 2-wire trick that is stopping the proper power getting to the eject part of the drive...?

Has anyone faced this problem? Is there anything that needs replacing to get it working again?
Any help is much appreciated. Thanks.

If it doesn't stick like that when a disc is in the drive then it's the belt. The thing in that drive slips and causes that issue, either remove and clean it real good or replace it and it should be fine then.

For got to add that wile the drive was hooked to the pc and functional i was using the xbox to power it,
im just at a lost and need help if anyone has reasonable input i would greatly appreciate it

just seems weird that it works fine in windows and acts as if it's a dead drive in the 360

i noticed that the power light flickers once when the ejection button is pushed on the xbox.
but for the most part the power light is solid green. few times when cycling the power it will then start to flash till i hit the eject button then it goes back to solid green

@ carlwep - This discussion is about the Samsung that was used to replace a Hitachi, the Samsung doesn't have a modeB either, so which model/version drive are you messing with exactly?

First thing to try on your problem though is to restore your drives FW to it's original state and see how it acts then in the 360. Make sure the power cable doesn't have any broken wires or anything either.

[carlwep]

it's a Hitachi 59dj.
now that i think about it the only thing i can think of that i may have done wrong is forgetting to ground the 360 case to my pc case.

I did use the 2wire trick for mode b.

I also looked just looked around on the mainboard not check with multimeter looking for burnt resistors or popped capacitors and see nothing.

I shale be doing a lot of reading today and if i come up with anything i will post back.

I appreciate all you input. lol shame i just bought a replacement drive  and the problem points to the xbox itsself

So I was doing some testing yesterday on my fully working 360 and on my 360 which has this eject problem

I was using a multimeter, and checking the voltages on each pin of the DVD drive power cable.



Referencing the above diagram.
I was testing my working 360
I only saw voltages on the lower pins. (1,3,5,7,9)
I saw a voltage come on pin 8 Only when I pressed the eject button. So I guess this is where the command from the 360 comes to tell the Drive to Open or Close.

When testing my 360 which does not eject.
I saw the same voltages on all the lower pints. (1,3,5,7,9)
But I saw no voltage at all on pin 8, even when pressing eject.

I tested around the board, while pressing the eject button, to see if I could find the power somewhere, but haven' found anything yet.

Would be a great help if someone on here who was familiar with the 360 circuitry could help me out.
Im no expert, and not sure if im looking for the right thing.
Someone please help.

Another thought for you carlwep.

you said that your DVD drive ejected when connected to your PC, but still powered by the 360.
Do you mean that you pressed the eject button on the 360, and it ejected? or you used software on your PC that made the drive eject?

If it was software on your PC that got it to eject, I would believe it to be the same problem as I am having, as obviously your drive is getting power, as it was able to get flashed, and also to open an close while being connected to the PC.

However when its connected to the PC, you are only connected via Sata cable. So if im correct your PC software is sending the drive a command through Sata and telling it to eject.

While on the 360, the eject happens by signaling through the power cable to the drive to eject.

So the drive isnt broken, but the 360 has lost that ability to send that Eject signal through the DVD drive power cable. Which is what Im trying to fix at the moment.

If anyone has any feedback on this, please do comment

correct when i hooked the dvd drive to the pc i went to my computer and right clicked on the drive letter and told the computer to eject the tray and it did. I also put a dvd in the drive and the drive would load the disk with no problem as well.

not only does the eject not work but puting a disk in the drive manually via emergency tray eject trick the xbox doesnt even try to spin the disk. no sounds come from the drive.

i can get the drive to make a noise as if it was trying to start in the xbox by attempting to put it back into mode b by putting 1 sewing pin on pin #0 and  and 1 sewing pin on pin#9  in the back of the dvd rom and shorting the connection for a split second  with a piece of wire.  but i wouldn't recommend doing thst with your drive since it is a different make and model then mine.

i was thinking that a resistor may have gone but who knows could be the whole chip that controls the dvd  drive function there are so many little resistors  to check and they are all so small you cant tell if any are burned out just by looking at them.
 I just went as far as removing the Mainboard from the case and checking  the sata port pins with a meter to see if the points are carrying a connection through the board.
 thought maybe i could have knock a solder point or pin loose
but in my option that is not the fault

Youre right, it could be anything, anywhere on the board that could have blown thats stopping the eject functionality.

You wont really be able to tell by looking at it, would need testing, and tracing back from the eject switch or from the connector it self. Will be trying that today.

I have the same symptom you mentioned, which is that the drive does not spin up at all, but it did when I plugged it into my working 360. So I know the drive is working.

Im hoping to be honest that the solution to the eject problem, which I expect is a dead component somewhere on the board, will also solve any other problem such as the drive not spinning up. I think that because the 360 board is unable to check if the drive is open or closed since there is no power going to that Pin #8, then the logic simply thinks that the drive is constantly OPENING or something like that. Once it has that functionality back, it will know the drive is CLOSED, and time to spin up and start reading.

As I mentioned in my previous post, I'm pretty sure that the eject command comes from the Power cable port, not the Sata port. The Sata port would be more difficult to break I think. So really I would check your power cable port on the 360 for power. Specifically check Pin #8 while pressing the eject button, I suspect that you wont see any power there as I do on my working 360.

If someone on here more knowledgeable could confirm the functions of each pin on the DVD drive power port, then it would be quite helpful, and also offer any insight into the problem.

I havent tested the power pins on the board yet im about to pull out some toold and the meter but if you get no power from pin 8 couldnt that possibly be for the ground?

[Solid Snake]

Its not simply no power.

I have tested the same pin on my working 360, and PIN 8 shows power only when the Eject button is pressed.

On my broken 360 it shows no power in any case.

Suggestion, plug the DVD power cable into the board, but not into the DVD drive, and test the pins by touching the meter to the connections on the cable, its less likely you slip with the meter and touch two of the pins together this way, you dont want to do that.

I havent had much chance to do much testing today. Might do some in a little while.

Was testing around the board for an hour last night. Didnt find anything  
I dont know enough about motherboards to be able to trace this problem I dont think, Im about to give up on it to be honest. At least I can still get into the dashboard, and maybe using it just a media center extender or something. I do have another 360 already, so fixing this one was just for kicks, but has been a bit a let down...

If anyone takes a look and finds anything out though please please post or let me know. Thanks.

If anyone looks at this thread wondering how I replaced my Hitachi drive with an MS28, As per the title.
Google 'Textbook tutorial 360' its a detailed tutorial on flashing any 360 DVD drive, and will give you pretty much everything you need to know.
For the MS28 itself, I had to solder off a small component on the drive, and install a switch between the two points. Then to read and flash the firmware using IPREP on a USB stick, you have to get a very specific timing right when pressing the switch as the tutorial tell you to. I thought it wasnt going to work at first, but it was just the timing, and I eventually got it.
