Pushing data to the outside of the disc - Quicker loading games?

[kevstah2004]

If you rebuild a PS2 ISO with all the bigger files such as movie files, sound etc at the end of disc it'll make the game load quicker is this true? as the read speed towards the end of the disc is quicker, patch the empty disc space with dummy data to shift all the files to quickest loading speed possible
I'm not sure if this would have any effect on HDLoader though.

eg: on a DVD-5
1-700MB Dummy data first file on disc.
2-1GB File
3-1GB File
4-2GB File last file on disc.

The moving to the edge of disc method is used quite often by game developers. It has been used for all optical media types and is meant to specifically improve loading of things like levels. In games like Tony Hawks American wasteland were no "loading" occurs the levels are dynamically loaded in the background this is even more important.

As for HDL, Dummy padding has no benefit as HDD seek times are very low and the HDD never "spins-up" like an optical disc.

[kevstah2004]

So it's a good idea to when burning ESR disc's you just need to adjust the LBA table if it has one?

[urbigbro]

I'm not really sure how to manipulate the LBA tables. Probably a person who is good at making CD-DVD conversions, or ripping tools, would be the best to ask for that. Those are the type of games that would benefit from it the most since they are small and would likely have almost all the game data in the very center of a DVD disc.

this theory is false

the data on the outer edge of the disc reads slower then the data on the inner edge of the disc. Why? Because the closer to the center the faster it can make a complete rotation.

THINK: two athletes running around a track, wich would take longer? The one running around the inside lane, or the one running on the outside lane? Obviously the one running around the outside lane would take longer to make a complete rotation around the track.

you are obviously wrong about many things, a HDD DOES SPIN UP. look it up on wikipedia, howstuffworks, etc.

Your right about a HDD spinning up I think but wrong about a cd/dvd?

Think about about this way, towards the outer of the disc the circle becomes bigger that the laser has to read therefore the speed becomes greater as it doesn't have to do as many revolutions to read the same amount of data. You runner will of beaten the outside runner but will have only covered a small distance in this case MB's. A bike with a biker cog will travel faster than a bike with a smaller one.

[urbigbro]

As far as I'm aware HDL doesn't ever spin down the drive once a game is loaded. I have never heard it do so in the years I have been using it. So spin-up time has no actual effect since your HDD spins at a constant speed once initialized.

As the entire game industry already knows kevstah2004's facts are correct about the outer edge loading data faster.

This information and other topics such as, media quality, and how burn speeds effect data integrity, can be better explained by visiting a site like club cdfreaks. They have extensive test data from real world tests.

@jengo: I'm not trying to spread misinformation about how a HDD works, merely focus the conversation on factors that actually effect HDL game loading performance

[TnA]

@urbigbro: (Retail) HDL for example does spin down the HD (that´s, why there is an Anti-HDD-Spindownfix out there...), after some minutes not playing (thought.. 20minutes).

You´re right about CD/DVD.

If that happened the outer disc would be spinning indepently to the inner. Imagine like you said, two runners, one on the inside, one on the outside. They would be running parallel to each other, so the outside one would oviously be going faster. But which one covers more ground (or track if you like)?
The outside one does
