xbox discs (Page 1 of 2)

Hi,

I have 2 copies of the xbox version of Jaws unleashed (Europe version), however they both fail ripping at around 40%. Is this just a coincidence, or do xbox discs have a known issue that causes degradation?

One of the discs is clearly rubbish (the print side has some see-through bits), but the other one looks pretty good to me.

Should I try cleaning it and see if it rips, or what? As these are rare, (and expensive) I want to be able to send it back if it is damaged, so don't want to do anything to make things worse.

Thanks.

Edit: Actually, they both have print-side scratches. Back they both go!

But question still stands - do xbox discs have any known degradation issue?

wiggy2k also has 2 copies of Jaws Unleashed that he was having trouble reading (he does have a polishing machine now though. Not sure if he managed to fix them) either that's a coincidence, or there could be another reason for the errors than scratches/degradation (also in light of this discussion: http://forum.redump.org/topic/15998/ori … ergh-disc/ )

Could you share the SS.BIN, and tell us at exactly which sectors the errors start on both discs?

If the errors occur outside of any of the 23 security placeholder ranges, then at least we know that our dumping method isn't to blame.

Edit: Funnily enough, I've been speaking to JayFoxRox about this on the xqemu IRC. I'll read that thread properly later.

I don't remember that; what's your nick / time so I can check what I said? (I keep logs because I tend to forget a lot of stuff )
Also don't waste your time with that other thread - that is not the issue here.

Seeing how those fail at different addresses, this just sounds like a bad set of discs. - however, 3 broken discs (what Jackal said) of the same game does sound strange..

Do you have more information about each disc?
If they are the same, we might be able to just dump the broken sectors from the other one.
Also dumping at least parts of the discs, would still be a lot better than not dumping them at all (the information printed on the disc would be of interest so we can rule out a massive fabrication error if others have similar issues + partial hashes for the data track should be enough to generate a full hash later on if some people have the same disc).

Also I've checked the remaining SS range entries and they would equate to:

-7970541-3620644 # Garbage [negative = value too large]
929056--639302 # Garbage [negative]
-5647194-1871508 # Garbage [negative]
-4878751--9782664 # Garbage [negative]
1651512-1310022 # Garbage [start after end]
-10166893--2467619 # Garbage [negative]
-811541--8662161 # Garbage [negative]

So it indeed looks like only the first 16 entries of the SS ranges are used (Also both SS range tables match).

Another thing: What drive / FW did you use to dump it?

Personally I'm not aware of any degradation issues with Xbox games, but I haven't really looked into it. Keep in mind that those games are 15+ years old now. However, I noticed that I have a couple of games which have a broken Xbox DVD hologram. Somehow the plastic looks like it splittered internally or somehow (internally?!) was covered in oil. I'm not sure if the games came that way or when it happened. They still work fine though.
(See http://i.imgur.com/AZmmTUt.jpg - it looks a lot more severe in person, the scan doesn't do it justice. The hologram is almost gone at that point and you can just see-through the DVD)
However, this probably deserves a different topic altogether.

Good luck. I was getting into the £50 mark. Also checked cex in Wrexham this afternoon just on the off chance. Nothing, though.

Well I despair with this game.
This copy couldn't be in any better condition (see picture attached) but still fails with sense error around 15% with one Kreon drive (sh-d162c) and around 35% with another (TS-h353 cross flashed)  have tried around 5-6 attempts on each drive so far. Both drives have been fine for dumping other Xbox discs.

Gonna strip an old Xbox down and see if I can get an original Xbox drive attached somehow.

In case someone can do a better job.

IFPI 0784 < added as 07B4 (could be wrong)
IFPI 0739 < that's the best I can make of it too
