Comment on Read your DVDs the RAW way… by Owen

Excellent hack!
I have one of those drives and finding the data lines is easy enough. However, I don’t have (and can’t find) the datasheet for the MN67703 chip (or any of the others). I even asked panasonic (the manufacturers) if they could pull the data from their archive. They don’t have it they “claim” (too lazy to get it is the real answer).
If anyone out there reading this has even a pinout of this (or any of the other chips), I would appreciate it.
With so many pins on this particular chip, surely the data stream is not the only interesting data ‘decoded’ from the RF stream! What about the data in ADIP or pre-pit? The wobble frequency? All those extra goodies that are available only when you get down-and-dirty with the raw disc!

Getting right down to the level above RF is probably as far as I want to go when doing data recovery. “data-fade” is becoming more and more of a problem with DVD+/-R/W as “archive” and backup material is being pulled for restoration. The DVD (R/W) standards are fairly prescriptive about things like where data sectors start/end in relation to groove wobble and ADIP data. When the actual ‘burnt’ data is unreadable, the drive may not find the start of a data sector in the raw data stream, *but* the ADIP data will still be available as it is laid down in the mastering process. Feeding all that data into a software decoder may contribute enough data to find ‘missing’ sectors (eg: sync was missing) and decode at least some of the data in the sector itself…

Cheers,
Owen.

The DM800HD does not need all these screws to work

Yara does a pretty good job of this as well, with some additional features to combine rules. Yours is certainly a more posix-friendly implementation, though. Cheers.

Hello,

I followed your instructions and i detect the
XC9572XL (initialize chain), but there are no Operations , like program or erase.

Best Regards,
Daniel

I don’t think it’s “kaijyo!?” since it appears the first byte is a prefix of some kind, if you compare the string to the other challenge questions. Therfore, it’s actually “aijyo!?” which translates as “love?!”.

btw, have you seen http://freedreno.github.com/ ? Based on the descriptions I have read of the xbox gpu, it sounds quite similar to xenos. I suspect adreno/imageon gpu is derived from xenos. So maybe the work on opensrc adreno driver helps you?

Chipscope with a generic FT2232 cable?

OH MY GAWD!!!!
Sooo awesome!

Now we just have to patch this into xc3sprog to support all kinds of cables without source mods.

Hey, I created a program in Python similar to yours. Great work!
