Hitachi v78 and v59 with LT+ 2.0 Unrecognizable Disc Error on XGD3 Backups

I updated my Hitachi v78 and v59 consoles to the recently released LT+ 2.0. Some of my XGD3 backups show an "unrecognizable disc" error when I try to play them. The strange thing is some of the backups work on the v78 console and not on the v59 console and vice versa.

However, all of these XGD3 backups work on my other console with a Liteon 0251 drive with LT+ 2.0 with no problem.

All three of my consoles have the 13604 dashboard.

Has anyone else seen these errors after updating to LT+ 2.0? Any ideas on how to fix it?

No xgd3 will play on 13604 dash.. You'll have to wait for lt 3.0 to be released. Unless I'm mistaken

You are mistaken. I have 2.0.13604.0 on my Jasper console with the Liteon 0251 drive with LT+ 2.0 installed. My XGD3 backups work on it with no problem. I do not go online with any of my consoles so there is no chance that it was updated without me knowing it.

You're probably thinking about the 2.0.14686 preview dashboard update or the 2.0.14692.0 silent update that came after. After these are installed, it is suggested to wait for LT+ 3.0. I think. Can anyone confirm this?

pre 78 hitachi should be fine my guess is you hitachis' lasers are weak they are notorious for this. you should do a pot tweak as joe singer already suggested. even if you had a brand new laser it might not read the backups in a craptachi. i've literally taken a new laser from a hitachi that would not read a game and put it in a sammy and read the same backup the hitachi would not.

I have performed a pot tweak on the Hitachi v59 a few months ago because it would not read any backups at that time. The pot tweak was able to fix this problem.

If it is the laser on both of the Hitachis, wouldn't they be unable to ready any of the backups at all?

My problem is with just the XGD3 backups. The Hitachis have no problems reading any of my XGD2 backups.

still have to go laser. you say (backup 1 plays on xbox1 but not xbox2) (backup 2 plays on xbox2 but not one) right? you say that backups 1&2 play on xbox 3 that is not a hitachi. this points to the laser.how far did you push your pot tweak? can you go any further?
the only other thing i can suggest is look at your backups. are you burning 1 to 1 with ihas or truncated? are you burns verified through kprobe?

Yes. That is correct.

The pot on the Hitachi v59 was originally 3.986 k-ohms and I lowered the pot to 3.225 k-ohms. The pot on the Hitachi v78 was never pot tweaked. The backups were burned 1 to 1 with an iHAS burner. The burns were verified using IMG Burn but not KProbe.

3.0 is as far as i would go. as far as your backups go this is what i used to to setup image burn ( http://www.se7ensins.com/forums/topic/596479-how-to-get-non-verbs-working-with-lt-max/ ). i use cheap disc memorex and kodak and with these settings @ 4x my games have all been solid. try verifying your current rips with kprobe

I'm a dedicated Verbatim (MKM) 001 user. These are the 2.4X DVDs. I'll try the KProbe. Aside from containing more data burned on to the disc, are the XGD3 discs burned so differently than the XGD2 discs as to cause reading errors on Hitachi drives even with right pot settings?

Another strange thing that I discovered is that the backup of a Battlefield 3 Campaign disc can be read on one of the Hitachis but the back up of a Battlefield 3 Multiplayer disc cannot be read on the same Hitachi.

I did some pot tweaking on the Hitachi v59. I originally had 4 backup XGD3 discs that were giving me the "unrecognizable disc" error. After adjusting the pot down to 2.989 k-ohms, I was able to get 3 of the 4 XGD3s to work. Is it advisable to adjust the pot even lower to get the four backup to work?

I downloaded KProbe2 to check my backup. I took a look at the tutorial found here: http://forums.360mods.net/showthrea...burn-quality-testing-tool&p=161188#post161188

I found this tutorial overwhelming. Is there another more simplified set of directions for KProbe out there that will tell me how to check my backups with KProbe?

Same here. I just pot tweaked my Drive to 3.2ohms. The back ups still don't work. :(

Do you mean 3.2 k-ohms?
Try adjusting the pot lower. I read somewhere that you can adjust the pot down to 2.8 k-ohms. Make sure you set the range of your multimeter to k-ohms and not ohms.

yes it is k-ohms. I tried as low as 2.9 and kept getting disk unrecognizable for all my backups (old ones worked fine before). Could my DVD burner be the problem? Its a samsung and i was reading the Kprobe tut and i think it said that it only works on Lite-ons.

simple things you should check with kprobe

XGD3 Quality Benchmarks (per TX and C4):
PI MAX should be 100 or less & PI Average should be 5 or less
PIF MAX should be 4 or less & PIF Average should be 0.20 or less
Nero Discspeed score of 90 or better.

also i've never gone lower than 3.0 ohms becareful and always install games to hdd, bye tweaking you laser it will die faster don't use except to install games.

you are burning truncated games meaning not a true 1 to 1 rip which might be causing you problems, but bye looking at you posts i'd start bye re dumping the firmware on you drive and making sure everything is ok. make sure you 1) installed the lt2.0 firmware 2)spoofed key to the new firmware. the only two things i can think that would cause working backups of xgd2 not to work after after a firmware update.:duh:

I think you misunderstood me. When I pot Tweaked my drive to 2.9 none of my backups would read. Once I tweaked it back to 3.11 they all worked beside the Xgd3 games. I flashed the drive about 4 times on 3 different computers. I really don't think its the drive. I think its the way I'm burning the Disks.

The way I burned the backup was, Edit the .dvd file change the layerbreak to 2133520. Load the .dvd to imageburn and burn with truncated. I use verbatims (Singapore)

Why would i have to Spoof anything if this is the original drive that came with the xbox?

i went back and looked at the nfo with the 2.0 release and pulled this ( Support for XGD3 ixtreme backups using LT-MAX for maximum capacity on standard DVD+R DL discs.) i could be wrong but looks like it might not support truncated backups. can any one confirm this?

what i meant by spoof was after you dump you ofw and open the hacked firmware you have to hit the button ( spoof source to target ) to auto spoof the drive which will place your key in the hacked firmware tab before you write it to the drive
