My copy of Call of Duty 3 has a legit crack in it, and yet it plays perfectly fine. I’m serious, not a single problem.
Yet, my copy of red dead revolver has a little scratching, nowhere near perfect, but there are games with more and play fine, such as my cracked call of duty, and yet red dead revolver won’t even fucking start.
Explain how something like this can happen.

No. Some answers you must seek yourself, you'll find it in the midst of your journey.

Call of duty 3 only took up half the disc while red dead took up all of it

How did you crack your disc doofus

Bought it in a bundle of ps2 games for like $10, mst of the games had scratches. Some minimal, some not so much. This is the only one with a crack.

Discs are read by a laser reflecting off of the back of the label. If any kind of scratch, scuff, or mark blocks the laser enough for it to be unable to read the disc, then you'll have issues. Sometimes a scratch does block the laser, but only blocks reading of some nonvital data that the game doesn't require to function.

Black Ops 3 doesn't actually read from the disc after it is installed. The disc is just used as a form of physical DRM after installation to ensure that you still own the original game disc.

I once had a disc with a crack in it. I kept trying to force my cd player to read it until it shattered into a hundred tiny pieces inside the player. Fun times cleaning that out.

This is call of duty 3 on the ps2 though

I've had two disks crack in my old 360.

very, very basically discs are essentially layers of foil trapped between a matrix of plastic with tiny holes in it. If a scratch obscures the laser's path to the foil it will not be able to get any useful information from the result.
The laser and disc are smart though. It's got the (limited) ability to account for the occasional bit of data it can't read or understand.
But it is still a machine, and is only as capable as the fumbling hands who birthed it in the milling fields of a thousand automated midwives. Sometimes the laser cannot look past the scarred visage of a grizzled disc, and see the wonder inside. Sometimes it can lovingly kiss the data underneath 3mm gouge, sometimes it leaves the surface-grazed disc alone to a life tethered to its plastic polypocket or pillaried to the plastic spool.
Truly the fate of discs spins and spins, x32.

Why would they include nonvital information on the disc? I was under the impression that devs had a hard time as it was fitting everything onto one disc.

This was oddly beautifully worded

Well for example if the scratch covers up a region of the disc that contains data relevant only in the singleplayer portions of the game, you would still be able to play MP with it, and it would just freeze when you reached those portions of the SP game. So while the disc stil works, certain parts of the game might be inaccessible. It could also just be ambient sound effects or some such and the game simply skips playing them without you noticing, or some other similar situation. Sometimes portions of data are corrupted but the game can read it anyway without issue. Sometimes there's simply no data behind the part of the disc that was scratched, because many games don't take up the full space on the disc. There's no way to know for sure.

This is closer to the truth. CDs are encoded in a way that means that you can fuck up and it'll still get the data. For example with NRZI you actually expand (dong) the data over a wider area and this helps prevent your disc fucking up.
Imagine a target ten feet away from you. You have to strike it with a plunger gun and make it stick to get a cookie. If the target is small you are more likely to miss than if the target is big. This is what causes the problem you mentioned, that takes up more space than the smaller target.
So why can a tiny scratch fuck things up? Well imagine a series of big and small targets at a range. You have to hit all of them to get the cookie. Now a scratch is some pillock standing in the way waving his dick around in front of the target. You'll probably be fine with the big targets, but a smaller target, or small bit of data will be harder to hit.
So in short, semen can be used to fill the gaps in your disc, and never EVER buy one of those disc cleaners.

I haven’t noticed any music cuts, multiplayer issues, or single player issues. I mean, it confuses me, really.

This just in discs are finicky as fuck.

Those were just examples. It could just be like others have said that the game can still read the data around the scratch. RDR is a much larger game in terms of data than CoD3 so it wouldn't take much to cause a fatal read error in it compared to CoD.

Really says a lot about your game when it has so little that a crack does nothing to it.
Thanks for the help guys.

CoD3 was made for CDs, not DVDs, so it makes sense.

Don't forget that if it's a console game, data will be duplicated all over the disc in order to lower load times. Can't load gunshot01.wav from sector 21108? Go find its duplicate in sector 14519

My copy of Red Dead Redemption has no scratch and also it doesnt boot up. I guess it has to do with time?

I play all my games cracked and they work perfectly fine

>mfw my copy of black ops 1 was manufactured incorrectly and over time the lazer destroyed the disk, slowly corrupting the data on the disk, making it unplayable

The data is stored on the foil.

Nigger why are you wearing a winter hat in your room?

How thin can I have a single disc scrubbed before it stops working?

It’s cold

The plastic layer on the bottom is just there for protecting the foil layer that actually has the data on it. So the answer is "pretty fucking thin".
It should also be noted that the underside of the label is literally the foil layer.
Some people put their discs down on tables or whatever upside down? DO NOT DO THIS

Does it have disc rot?
