Surface scan & unreadable sectores

#1

hello to you all.

i am FREAKING here, please give me some advice…
i try to backup my ps2 games. i use DVD decryptore to extract the data to an image. i then use either nero ,Alcohol 120% or DVDdecryptore to burn that image to a dvd -R.
on every burn i did, the game was not loading proparly or was stuck sometime after loading. then i started testing the discs with cd-dvd speed ScanDisc,
since my NEC 3520 can’t use the quality test yet.
i was burning the games on X2 speed on TEAC DVD -R media that with CD speed info tool it claimes to be TYG02. the serial number near the hub reads:T1017.
on every surface scan i did i had about 45-55% unreadable sectores!!!
allmost all of the errors started after about 40% of the disc check.
well, i thought that explains why my ps2 slim couldn’t read them!
then i checkd the burn with a few movies i had. i filled the DVD with appx 4.5GB of data and burned it in nero. after the burn i checked again with surface scan and i had 0% unreadable. a perfect disc, right?!
well, guess again!!
after 10 minutes i ran the surface scan on the same disc. this time i had about 30% ureadable data!! what the hell is going on?!
i tryed making an image with nero of some data i have.
again when burning the image with DVDdecryptore and checking it on CDSpeed surface scan i had about 45% unreadable Errors.

Is it the Media??? Is it my new NEC 3520? Is it the hand of god?

your help will be much appriciated…

Do you have a way around the copy protection like a mod-chip or fliptop? Without those it will not work. I would try some different media, there are some fake TYs floating around.


#3

yes, i have a mod chip.
maybe it’s the media, i dont know. teak considered to be a good brand, no?
is there a tool exept cdspeed to check media quality?
Kprobe doesn’t work with my drive, dont know why.

I’m using almost the same setup as you and also have a NEC3520 myself and have been using Datawrite Titanium disks since they came on the market. Unless it’s your software which is f****** it up, I would recommend trying this particular brand.

thanks, i am using intenso discs which are good and stable.
it works good.
it’s unbelieveable how bad TEAK discs where…

I bought a pack of TEAC drives and they say the exact same thing on them. Actually im pretty sure they are the same media. I burned one, and guess what, no dice reading it. I have a 3520a too and i am using the same boxed media. It’s nuts. The first pack of 3 boxes of 10 i bought was Prodisc F01, i pop this one in and i see TYG02. I say yippee quality stuff!
I guess not…
They cost me about 7 bucks for 10 of them.

Taiyo Yudens are usually good quality (costly!) media, however I remember reading there was a dodgy batch or series of them lately which were sold under different brands. One of the more regular guys will probably be able to advise on which MI codes are linked to these.
