pushingthe pots is a dirty way whic can be used on afaik every drive. i always use it to push older ps2 drives.
i dont know a pc version of the philips which means that i dont know if the pc version would have read cds. sure, the philips is only made for the xbox but its not said that MS ddidnt build some disadvantged into. thats the main idea.
as the firmware is encrypted on all drives all drives 'could' have some locks.
think of the samsung which dont read dvd+ in general, do you really think that you'd need an other chipset / laser to do that?

[menelik]

yeah, new sammys are a good aim. as i work for a modding shop i wll get my hands on them soon, just a matter of time. the second questions is if it will be as easy as this one here.
do the new sammys read dvd+ ? someone told me that some sammys (maybe oder too) read dvd+ but i never get them to read.

[TKramka]

Nor I, but I do know that 50 ohms off a Philips works every time, and the only Philips drives for PCs are DVD burners, and a select few, only about oh 5 models per say, but no one is going to want to give up dvd writing for XBox game compatibility.  I am not sure so don't quote me on this, but new Sammys don't read CDRs but do read DVD+Rs.

[TKramka]

Do you have any of the 8050L mainboard, I want to track down VRCD on that thing. Also, can you get a shot of the underside of the Sammy laser?

[TKramka]

It really is good, especially with the new pics, kudos to you my friend!

i mailed a mod for a pin but got no answer yet. moreover a post to the news would be nice; i think that many people are searching for something like this and will never know about it. im afraid that they will recognize the mod when the 8163b isnt available anymore.

One more think i have done with the drives i have moded , is that i removed the the light lamp from the front of the DVD drive , its not needed anyway and now the drive fits better in my xbox and comes more forword.

While not as hot as XS, I would love to put this in the front page of my site

To be precise the DVD+R I use are Platinum 8x DVD+R burnt on a Plextor PX-716A. From what I hear the various Xbox drives have a problem with media burnt on Pioneer DVD burners, that's why I got this Plextor.

The Platinum are in fact Ricoh's media.

udapte: phillips 6035/21

the story of the drive: i got this oe from a crystal box, i ushed the potis 8 months ago and it worked fine, even with the most cds. in the last months it had more and more problems and wasnt able to read many of my dvds. so i started working on this. at the end it read really everthing, eqaul which media, even 6 year old cds. main problem is that i dont know of any long term effects...i dont wanna publish more as i cant proof that it wont let the drive die.
just wanted you to know this ability.

i need someone with this drive who takes the risk and tries this, please mail me.

I suspect that there may be another way to accomplish this.

I'm not looking to start a fight so let's not get upset. I have not evaluated the electrical reliability of the CDR "fix" at this time. If it does affect laser bias, it will most likely decrease drive life as menelik suggests.

Perhaps this thread should have not been split just yet.

Ok i am ready to attemp this mod

i wanna get some things clear first ,In the tutorial the author said u can use a y splitter if u are ignoring the power wiring. i know this is the 5v and 12v points, but i wanna know if i can ignore the grounds(gnd) point too if i use a y splitter

second: the wires i am planning to use are strip ide cable wires is that ok

last question: i have some 1k risistors that are the spiral colour stripe ones not smd 1206 versions can i still  use these and get cdr support

[menelik]

@liteon6x

1. no, you dont need gnd
2. that wires are ok
3. it doesnt matter what kinda resistor your take, the values have to be the same

@tiros

i've never said that this solution is a digital one, im quiet sure that its analog.
anyway, its not definetly said that the m$ firmware doesnt decrease somehting from the laser which this trick equalizes. moreover im not playing directly with the laser bias, this would just be a normal poti push.
my problem is that im really no expert on laser diodes; anyway, i think that this solution affects the laser pulse. normally you got two pots with two functions, laser strength and pulse (different to ps2 which got one for cd and one for dvd). so i tried to set the laser pulse manually within the pot on a philips which ended in reading fine on cds but no dvds anymore. then i used the vrcd trick on the philips and it reads fine everyting. i've measured the laser strength and couldnt see any difference to before.

and no we didnt split up the topics to early because the last one really really got inscrutable.

[menelik]

im afraid that this get my new diary, anyway:

i measured around with the philips and cant imagine how a pulldown resistor (from which i think it is) could damage the laser. moreover i measured lower voltages when i used the resistor to ground. once again, im not an expert but i dont think that dropping the voltage will let the laser die. when i'djust push the laser through the normal pot tweak the laser should get a higher voltage.
please share your ideas.
