Ive made a tutorial for all those people having problems with their discs
  • Dirty Disc Errors
  • Games crashing half way through , due to reading problems
  • Discs sometimes loading, and sometimes not being recognised
  • the classic "OPEN TRAY" problem
  • and also glitching FMV or slow loading games (some games are just slow, its normal so be patient)
Please remember to test the disc on another console to ensure you have burnt it correctly. This is so you dont go and adjust the pot when its actually ok.

Download from the link below..

I will release a much better looking tutorial with a guide on what media is good/bad , which brand dye to go for etc , this should be complete in the next few days. in the meantime if this tutorial is any benefit to you please post here.

also.. please let me know if there are mistakes in this tut so i can correct them ASAP


Thanks
Moda

Thanks moda. I'll probably try this out soon. Last night I played COD2 for 2 hours and then I couldn't get a backup to play at all for about 4 hours.

Great Tut, but too risky for me. Is there any other way to fix this except for pot calibration?

the pot calibration is specifically to help against poor performing laser units, there are other ways, buy better media (always best thing to do, better media = less stress on laser = laser lasts longer)

burn at a slower speed = fewer write errors = better readability.

bear in mind, the lasers for the xbox 360 are cheap, in uk they are only 15 from mrmods. so if u burn it out, no problem!

Hi!
Here is my findings.
I've got 3 different media: Ritek, Verbatim, Ricoh.
Ritek and Verbatim runs only once, when a box is cold.
Ricoh is better, but not perfect. Sometimes it says open tray, but not very often.
Original pot value is 4.4
The tutorial says try to change 100 ohm at once, but this is very little.
So i can change 200 ohm.
In 4.2, ricoh works perfectly, but ritek and verbatim just changed a little.
so go down to 4.0 and ritek and verbatim works like the ricoh in the original state.
This is good for me, i dont want to burn my drive.
AND I think RICOH is good media, for example TDK DVD+R DL is RICOH.

bye

Werda

Will calibrating the pot of the dvd drive changes the drive durability? Would it make it more likely to be mess up quicker or do people have not experience any problem? For Those out there that calibrated their Pot, and play the backup games for like 2 hrs and try changing the game, does it give an error? I'm just wondering before i do this because this is my first time.

I have just tried the Pot calibration.
Well my original setting was 4.26
My media are Verbatim,Traxdata and Ridisc(CMC MAG.D01) , all media are 2.4X
Pot on 4.26 Verbatim read ok on cold boot , some time it gives "open tray" when change discs( have to turn of XBOX360 for 2-3 min, then it boots), Traxdata no boot, Ridisc only cold boot(with dvd already in XBOX360)

First i put the pot on 4.08, traxdata could read only on boot , Verbatim all the time and Ridisc most of the time.
Then i made it 3.90 here Verbatim and Ridisc boot all the time, traxdata only on boot.

Well i think now everything is much better, i am going to use Ridisc media(here in Greece 2.4 Euros) and not Verbatim(4.9 euros)

Ive been doing some more research into drives and getting all brands of dvd+r DL to boot.

ive come to the conclusion that if your dvd drive is set to 4.00k ohms or more from the factory you will have a far better chance of booting most brands of media without errors. (or maybe it is that HLG laser units are better made?)

i came to this conclusion after i had a TS drive which wouldnt play ritek dye or MCC dye regardless of how much i tweaked the pot. so i took a HLG drive and swapped the laser unit from within the drive (these can be swapped with any brand of drive)

original TS laser unit was set to 3.59k ohms (regardless of how much i tweak the pot it doesnt read ritek or MCC brand dye - pot tweak doesnt work)

swapped in HLG laser unit reads 4.15kohms (reads all brands of media i have thrown at it so far)

you can try this yourself, you just lift the screw from one of the guide rails of the laser unit and slide the unit out. swapp the guide arm around so it fits your drive (peice of plastic with a spring on it.)

I hope someone finds this information useful, please try it and let us all know if it works for you.


oh and one more thing, you can buy spare laser units for very cheap so if your having problems reading your media just buy a new unit from someone, they sell them on a popular modchip site in uk for 15 pounds. im not sure how much in $tate$
