GTA4 gave me an error. So went down to 4.05k. Installing to HD atm to test total disc reading

justeri · « **Reply #226 on:** April 08, 2009, 04:23:00 AM »

I went all the way down to 3.03 from 5.29 and did not have better reading for Traxdata nor Imation discs, Verbatims still read without any problems. So solution is obvious, ill buy pile of verbs and stick with them.

I noticed once interesting thing. If you play game or try to copy it to hard disk, and it gives error. You have to boot x360 before youll get good reading even for original discs. So there might be something like max retry times before it states error. Because backup disks seems to have loads of reading retrys and when that max out, you have to restart X360. Correct me if im wrong. That could have been added with the dashboard updates or so.

Thank you Moda for this guide.
Calibrated from 3.8k to 3.2k on a Sammy MS25 and all my Verbs are working again.

I've got a phillips-liteon drive that started giving me DDE and open tray errors today, cleaning the lens didn't help so I decided to try the pot tweak. It was originally at 6.2k ohms when I started and I've tried bringing it as low as 2800 with no luck so far. The red light still comes on so the laser itself isn't burnt out. It's an unmodded system, I just want it to play originals. Any suggestions? Can I go lower than 2800 safely or is it a waste of time at this point?

Waste of time, buy a new laser.

By mistake I moved the cd pot adjuster...
Does anybody know what a good value for the CD pot should be?

digichamp · « **Reply #232 on:** July 19, 2009, 02:01:00 PM »

has anyone tried changing settings with out a multimeter

tbone_99 · « **Reply #233 on:** July 20, 2009, 07:46:00 PM »

You need a multimeter...plain and simple.
Turning the 'pot screw' just a fraction can change the pot value a lot. You'd never be able to do anything by just using the naked eye.

my drive wasnt reading backups, i adjusted the pot without a multimeter with success. i did it twice moving it a smidge each time. I was just impatient and probably should have waited and got my hands on a multimeter.

very great tutorial for anyone with some intermediate skill. My friend's Hitachi wasn't reading backups and was very picky with retail games. I adjusted from 4.2K to around 3.2K. Afterward everything worked great. He got unlucky though and red ringed 2 weeks later.

none the less excellent tutorial.

To anyone doing this I would recommend upgrading to a 120 gig HDD and installing your games and backups to it. It greatly reduces stress on the drive. There are great tuts on this forum to do that for +/- 50$ instead of the 150$ official xbox 120 gig HDD

anyways thanks for the tut

Great TUtorial

Thank you Moda

I would like to add for BenQ guys that the pot is still the left one but the "left leg" equivalent for finding the resistance is actually the RIGHT (or the top if you're looking at dvd drive face up on a flat surface). So touch the left side's top solder and the pot and you'll get a reading that works. It's not the bottom solder leg (which would be the left if you look at the pot 90 degrees to the left) which is what's stated for the samsung.

I hope this helps

Worked awesome for me.

Props Moda!

Ya my benq was stock at 6.5 it wouldnt even read new games and it was loud as heck. I dropped it down to 4.5 and it reads anyhing and is very quiet.

Also to anyone going down lower than 4.0 and still having problems, You may want to try cleaning the laser lens if you havent already.
