GOW Backup on Samsung ---> WORKS
GOW Backup on Hitachi ---> Unplayable Disc
COD3 Backup on Samsung ---> WORKS
COD3 Backup on Hitachi ---> Unplayable Disc
SOME of my backups that work on the MS25 _DO_ work on the 0059DJ (including Tiger Woods 07).
I'm thinking of calibrating the POT on the 0059DJ. My question is, has anyone had success doing a POT Calibration to fix the "Unplayable Disc" error on a Hitachi, or is it only effective for an "Open Tray" error?

I am noticing the same thing. My friends have samsung drives and they read everything perfectly and without hickups ...
I am getting problems with some games.... Gears of war i wouldnt be able to tell you.. it isnt out yet, but splintercell DA is giving me trouble in the hitachi, and TDU isnt fail safe either. They work, but it takes multiple tries where the samsung drive reads them perfectly...
I was thinking about :
1. Pot tweaking, but i havent found any tutorials for the hitachi drive.
2. Buy a replacement DVD... i looked on the internet, but i cannot find a dutch store which sells them ....
If i dont find a replacement drive online, i think i will try the pot calibration this weekend when i got the time....
Hope to hear some responses from other persons....
With kind regards

I can't get my backup of GOW to work on my 47dj with Garyopa v2_to work. Would the rubberband trick help?
Havent tried this yet, but i am sure gonna try this this weekend....
Working at evening hours with stuff like this can get me frustrated.. at least at a saturday i can spend all day trying ...
I will post results .....
IF rubberband will not work im gonna try a pot tweak ....

tried the rubberband thing in my lunch break so i didnt have that much time...
must have done something wrong there i guess... I used a wide strip and then i had to cut it down to a very small strip of rubber.... no result yet...
same thing... i insert the cd... it makes a grinding noise and i am not able to eject the disc afterwards...
But as i said, i didnt have that much time.. will try again this evening...
The strip i used the last time was very narrow, and i was afraid i would break it while making a knot but it didnt....
Anybody knows if u need to screw the case back on to test?
Will try this evening.... i even have a multi meter at home to to that if i go crazy with that rubberband thing...
will let u know results....

Before you guys go off ignoring me. Try Birdy 2.2 fixed. Just try it and see if those games now work. I think there is a problem with the media patch in opa.

That's an idea ....
I already got my drive laying open at home... so i will continue that first, to see if it works...
someone else who could try the birdie flash thingie?
B.T.W.. just looked at 10 pages of OTS (open tray syndrom haha) ... there was a very good idea in that post of using a spring from a ballpen .... great idea.. will try that ...

POT tweaking the Hitachi is exactly the same as the Samsung. The drives are nearly identical, physically. Once you get to the laser head, use a multimeter (set to 20k Ohms) to chech the resistance, and adjust the pot accordingly. A lower number results in a stronger laser. Tuts I've seen say don't go below 2.8, but mine's at 2.5 and working great(the actual pot for dvd calibration broke off, so I've got the CD pot jumpered to it so they share the same value). I'm not worried about burning out my laser, cause I've got another

Hitachi V47 flashed with GaryOpa 2.2
I'm having problems playing backups of COD3 and GOW.
COD3 plays for a a bit (30min to an hour) then will finally crash which loading a map (30min into the game or so). Upon a reboot I get the 'unreadable disc' error.
GOW bites the dust right after the Game rating screen.
If I let the xbox sit for a few hours, it will allow me to play again for a short period of time, at which it will then repeat the errors above. "Unreadable Disc"
I'm interested in checking the POT and/or buying a new/replacement laser.

Do you use the same points to tweak as in the Samsung guide?

Personally i dont recommend the pot calibration as it does work, theres probably just some FW mess-up that will get resolved soon now that everyone is talking about these errors.
Post by: scienide on November 14, 2006, 11:49:00 AM
i've tried making several rubberbands.. about 20 i tried...
Does this actually work on a hitachi ? I tried several pieces of variable thicknes, but it has to be really narrow or the drive will make horrible noises ...
With a real real narrow one, i could the drive to work as normally without making weird noises. But... no go with the hard to play backups
If that rubberband thing is working on my hitachi, i better try something else with spacer rings and stuff
I got the drive open at the moment.. so im gonna check out that birdie thingie someone talked about.. and if that doesnt work tweak the laser ...
I modded some of my friends xboxes... and all my bad working backups seem to run instantly on their xboxes....
Samsung seems to have best performance until now, but most hitachi's seem to work better than mine....
I'll let u know later about my results....

Okay... seems we've gotten a little off topic here. My point was that POT calibration worked for me on my MS25 to improve "Open Tray" errors. And my question was, has anybody used POT tweaking on a Hitachi drive to lessen the frequency of "Unplayable Disc" errors?

yes done 7 hitachis pot tweak definately works
1. vastly decreases open tray/unplayable disc errors
2. increases detection of differant media
3. tweak between 2.7-2.9

no probs whatsoever...
plays backups that have been made on Verbatim DL+R on
either a Plextor 716 burner, Pioneer Burner, and the Hitachi
Burner that's in my Dell Dimension 9150...
sounds like you got a shitty burner or bad media..

Thanks for the input, dynt. I will definitely try it.
LOL!!! Are you serious????? Did you read the part in my initial post about how these VERBATIM backups ___WORK___ on my Samsung MS25? Every backup I have ever attempted with my burner works on my MS25. They unfortunately do not all work on my 0059DJ, so I just wanted to see if anyone with similar problems on Hitachi could offer any insight (in regards to successful POT calibration).
The MS25 drive will read almost anything, it's the hitachi drive that has problems with some media/burners. I know for a fact the NEC burner wont burn good backups for the hitachi drive. If you updated the firmware to the latest and are using verbatim dl media it may work. If you've already done this, i could guarentee 100% that with the Pioneer burner, these will boot INSTANTLY. My backups from my Plextor NEVER worked even today with the latest firmware. Got the 111d Pioneer and i havent burned a coaster in MONTHS.
Pioneer 111d (stock firmware)
verbatim dl burned @ 8x
Hitachi 47dj w/ opa xtreme 2.2
NEVER A PROBLEM.
P.S. The POT calibration will decrease the life span of your drive guarenteed. There is NO NEED to do that, just use the right burner and it'll work fine.

anyways, am now back using my nec writer with mirror discs and all is good with pot at 3.48, odd that it runs better that way, but im not complaining!
Post by: scienide on November 15, 2006, 10:17:00 AM
i got myself a decent working multimeter...
opened up the dvd player ... again
Got the value of the pot which was 3,73 ...
I tweaked it down to 3.3 to start with, a save value ...
Put the drive half together.... hooked it up...
All my problem backups which run on Samsung but not on my hitachi are now working flawlessly ...
Pot meter adjustment > SUCCES ..
Hope this helps ....
Post by: scienide on November 15, 2006, 10:28:00 AM
some of my backups worked perfectly on my drive, on platinum and verbatim media..
some games however, seemed to have trouble running.. on verbatim or platinum...
Splintercell Da (pal) i couldnt get running with the combinations:
platinum - nec burner
verbatim - nec burner
AND platinum - pioneer 111
verbatim - pioneer 111
Neither of those backup booted ... not once have i been able to start this game...
Now all 4 of those work ...
Luckily for me i didnt trash the discs... was good testing material ...
Some of my other games needed multiple tries of eject insert to get the game working ...
Now everytthing boots.. without problems..
Pot adjustment will save me the frustration of rebooting ever and ever... wish i had found this earlier, my original splinter cell isnt looking 100% anymore
Thanks to everyone...

Thanks so much for the input scienide, and congrats on your successful pot adjustment. I'll definitely adjust mine once I get my potentiometer back from a friend who borrowed it.
Post by: scienide on November 15, 2006, 10:51:00 AM
my results with 3.3 are perfect... i've seen other original hitachi's perform the same way, so i guess the value of 3.4 would be a good value to start with ...
Keep me updated on your results....
Post by: scienide on November 17, 2006, 03:23:00 AM
I flashed this yesterday.... But ouch, this performace is terrible... dirty disc errors.. games freezing..
Looks like i got another pot adjustment project this weekend ....

I have tried EVERYTHING except the pot and rubberband tricks.
Too much to list.... again.
Thanks in advanvce man!
Also my 360 likes to gouge up discs a lot, will the pot tweak solve that... hitachi 46D Garyopa 2.3

have you tried burning them on a pioneer 111d, had the same problem ages ago with all my games, burnt on an NEC drive (3540a / 4570a) all worked fine on sammsy, but wouldnt work on hitachis (well on rare occasions would load, but then fail).
swapped to a pioneer 111d, working perfect ever since.
thought this was old news chaps.
as for everyone elses problems, with gow etc etc , not sure, but never had probs with any game, since changing to pioneer
Post by: PoksterG on November 24, 2006, 05:19:00 PM
It works on my Hitachi.
And so does COD3, and everything else I own. I can't help but feel a little silly -- after many coasters and many pot calibrations -- for not trying ImgBurn before ordering the new DVD burner. Looks like I'll be sending it back to Newegg opened, because my NEC-3530A is more than compatible with my Hitachi drive as it turns out.
Thanks all for your help.

That's odd, the opposite worked for me. I have a samsung ms28 with xtreme 4.2 and hitachi with max garyopa 2.3. Verbatims burned @8x with clonecd or imgburn work perfectly with either drives. I use pioneer 111D burner. i ran out of verbatim and was trying to use some memorex 2.4x form office depot. At first I used imgburn and only the sammy would read them. Then used clonecd and now can succesfully read in both drives.
Why would clonecd or imgburn be different if using manual layer break on imgburn?
