I have no idea, but I wouldn't be surprised if the "wasted" 1.7 GB includes the filesystem as well as other stuff which also exists on other game disc formats.

I would certainly hope they didn't use 1.7 GB just for DRM.

 

 

Although I am not sure if this is the case for the 360 in particular,  I was under the impression that game copy protection on the consoles in the past were implemented by randomly distributing errors throughout the disk whose positions the console's disk reader would hash and compare against a checksum stored at a known location. Obviously, the random distribution of the errors means that performance would neither be helped nor hindered.

However, I doubt the 1.7 GB is for DRM or FS overhead. If I had to guess, I would say it's likely mostly used to allow for better production yeilds either through larger Reed-Solomon codes or some other means.

 

 

Guys I've already told you....

 

The Xbox 360 uses about 7GB of the 7.95GB capacity.

DummyPadding partition is anywhere from 1mb and upwards depending on game data size.

Game data partition is up to 6.9GB

Video partition is the other 150mb -ish

The rest of the disc CONTAINS NO DATA ON IT.

The DRM is...

1. Unreadable errors placed in dummypadding partition.

2. Security Sector which is normally unreadable to any PC DVD drive, unless you own a hacked Kreon drive.

3. DMIPFI Sector, also placed in dummypadding partition.

That is all.

There is no "massive" protection totallying ridiculous amounts placed after the 7GB limit.

Please for the love of god stop making assumptions, guesses, being cynical, not believing me.

If you REALLY want to know...and you still don't believe me go and ask at...

This is such a basic question and answers that I can't believe you guys don't just eat what I say. It's not a debate, I'm not guessing, I'm telling you as it is. I have no idea why MS don't use more of the 7GB on the disc. But I can caterforically tell you it contains NOTHING. No data, no protection. NOTHING.

 

We clear now?

My appologies, your post was buried pretty deep in the thread and I missed it. However for the record I said I didn't think there was 1.7 GB used for DRM.
