Report: New Xbox 360 Disc Format Has 1gb More Space, Altered Security

Yesterday, I wrote this about the Xbox 360′s “updated disc format”: “I would guess the new format will either be an anti-piracy measure or something higher capacity than the dual-layer DVDs they use now.” Both possibilities were right!

Currently, a standard Xbox 360 DVD has 6.8gb of usable space out of a possible 7.9gb or so, with the last bit of space partitioned for security and video stuff. According to a Eurogamer Digital Foundry source at Microsoft, the new “format” will repurpose that extra space, allowing developers to use most or all of it. Presumably, the copy of Halo: Reach that will be distributed to folks in the format beta will be altered to make use of that space.

So there’s your higher capacity. The repurposing of that extra space implies new anti-piracy and security measures, but I’m not just working on implications. Hackman commodore4eva says this about security on the new format: MS will introduce xgd3 – this will add more ap checks, cvi (content integerity) checks, increase the disc size and adds a new layer for protection issues – all in the 20500 sdk! bring it on! :)

I don’t know what the hell that means, but it’s not the same thing they were doing before. So it makes me right.

Doesn’t sound like anything will change, space-wise. Developers were already padding the inner parts of the disc for transfer speed reasons. However, I can see MS updating their dev kits to make it more transparent to the developers.

It still sounds like MS is going to quietly start incorporating new security measures into the physical media. It would make sense to encourage developers to start using that wasted padded area to provide alternative security methods.

Here are some thoughts, with 1gb of extra space developers can create a sizeable amount of content (example: shivering isles (TES4 oblivion)which was huge plus a smaller disc to put content on pushes devs to get creative and technical on compressing files and data and pushes drive to make new, better algorithms to lessen the space taken by a game as a whole, its a good thing in alotta respects
