KProbe scan question

#1

Hey all,

I backedup a xbox game of mine. i have 411s. no i didnt hack it or anything. just like it the way it is.i have fs0j firmware. used the bitsetting tool to change from dvd+r to dvd-rom. anyway, i did a scan using kprobe (w/ default settings) and the spikes were HIGH! they were in the 900’s for P1 and about 300 for P0. I would attach an image but i deleted them! Ill try to post one if someone asks for it.

Are the spikes high because it is an xbox game? I mean XP doesnt even read the cd.

Oh, I have a Maxwell dvd+r and its ricohjpn

Thanks for any help =) Keep up the excellent work, guys

Hi Jigga73081

900 PI And 300 PO Doesn’t Sound 2 B A Very Good Burn.
But The Main Concern Is If The Your Xbox Can Play The Backup Copy.
U Can Sometimes Tell If U Have A Good Copy When The Backup Loads Up Just As Quick As The Original.

Here’s A Backup Copy Of Fight Night That I’ve Backed Up.
DVD Used Was A DVD+R 8x MCC003 (Mitsubishi Chemical Corp)

Jigga73081 U Mention That U The Default Setting In Kprobe
In Kprobe 2.1.0 We Use:
4x Speed
ECC Block Sum (PI/PO) : 8/1

And My PC Has No Trouble Reading The Backup Copy

well the backup plays fine in my xbox. i think almost as same as the original that i have. i was just curious that’s all

Pulsee: your Pi/po is 33/4 and mine is 900/3! thats a huge difference!!!

the speed setting was at MAX. but i changed it to 4x (i burnt the backup at 4x anyway). and 8/1 are left alone

anyway, here is the image. tell me what you guys think

PI Results Is A Major Concern
But Your PO Results Is Very Good.

MayB U Have A Bad Batch Of RICOHJPN01 Or That Your 411S Doesn’t Like Them.
I Have Done Some Of My Best Burns With RICOHJPN01 In The Past With My 812S.

That scan doesn’t look so great.
As a general rule, you want see PI errors < 280.


#8

But the POs are fine. Makes me wonder if it’s a problem with the reader… :confused:

Just 2 Quench My Curiosity

Could U Please Scan The Same DVD Thru Kprobe 2.1.0 With These Settings:
1x Speed
ECC Block Sum (PI/PO) : 8/1

2 See If This Greatly Reduces Your PI Error Readings.
:smiley:

Reboot Your PC B4 Any More Burning Or Kprobe Scanning.
This May Fix Your Problem If Your PC Has Been Running Without A Reboot 4 Several Hours Or Days.

sure will Sir

gimme a few minutes.

Also, when i backedup the orig game. the disc was dirty… like thumbprints and all that… i made a copy BEFORE i cleaned it!!! maybe thats why. but here…

1st image - the dirty disc game (before cleaning the orig cd)
2nd image - the good backup of another game (the orig cd was clean, no problems).

Hmm it seems with 1x its a MUCHHHHHHHHHHHHHH better result… woohoo!:slight_smile:

you can forget all the spikes on the PI graph
they are a mechanical problem in the reader
and likely not on the disk at all .
(see “spikey Liteon” threads)

RICOHJPNR01 vary greatly in quality from
tub to tub, it may just be a poor quality tub
giving PI in the 100-400 range. Should still
work OK as PO readings are fine.
