The whole point of a hot swap is to change the disk without the hardware being aware of the change.  If you hot swap the disk, no the 360 will NOT go back to the dash.  Depending on when the 360 tells the drive to look at the media type this could possibly fool the 360.  Can we test this, yes.  Make a backup of a standard xbox game, load the real deal into the drive, once the 360 knows what is in there, hot swap it with the backup.  This is not fool proof.  The 360 could make a record of where exactly the executable physically sits on the disk.  If there is a change, no love.  Got it.  Good.

swapping to boot a game can not and never will work. the signature of every executable and the media type is checked every single time its run, so even if you swap, it will verify the executable before starting it, fail, and reject the disk.

Mmmhh, just ripped KingKong with the swap method. CloneCD created a 7.61GB iso image. Checked the iso using an hexeditor and contains a lot of data. Opening the iso with DaemonTools or MagicISO i can see only the directories VIDEO_TS and AUDIO_TS....but I think that x360 data are really in the iso.... Will be nice to see if the rip works but no modchip yet to try  

Hi,
I'm the guy who released the procedure for hotswap dump.
First, sorry for my english, but I hope it's better than this horrible auto translation I saw...

This procedure has a problem concerning the second layer on a DVD9, because there is 2 way for putting data on a DVD-DL :
the PTP method, used for data DVDs, the layer 1 start from the center of the disc and go to the edge, and the seconed layer do the same. This shape is good for performances but at the end of the first layer you have to wait for the DVD player to go back to center of the DVD to start reading the second layer.

This is a problem while playing a movie DVD, because you can't wait one second during the movie ...
So there is a second way to write a DVD9 : the OTP method.
This time the data is from center to edge for the layer 1, and from edge to center for the layer 2.

All the movie DVD are in OTP desing, and data DVD are in PTP design, and I'm pretty sure the XBOX360 DVD are in PTP, so you have to use a data DVD for hotswap ... it SHOULD solve this issue, but I'm not really sure (I need to do more tests...)

But for KingKong, the entire game is only 2,3Go so you can (and must) do the hotswap with a DVD5, with only one layer. This time no matter if it is a movie or data DVD, because there is only one layer so no design problem.

So I hope I'm understandable with my bad school english, I'll send you an update after my second layer tests.

ok here's the problem. Someone said earlier to try to hotswap the disc. It's already been tried with a backup of Halo2. After being told what would happen the guy tried it anyway, and it performed just as thought. First, you'd have to let the drive spin down. This means to pause or not move for a little while until the drive will spin down. Then, you replace the original game with the backup when the drive is no longer spinning. Just so someone doesn't flip out, the only way this is possible is to take apart the DVD drive so you can remove discs WITHOUT ejecting. After you swap discs, start playing again. whoila! Everything works.....or so you thought. The game will play until the cache is cleared. Once the drive spins up guess what happens....error. You've been hit by a media check. Do not pass go. Do not collect $200. Do not think this will work.

This method is merely for a way to make the backups with a PC DVD drive...not playing them on the 360.  I did notice the DVD drive doing what you specified for DVD Video...it went center->edge for layer 1, then edge->center for layer 2.  I may try to make a large (almost full) DVD9 data disk for my swap disk, it should read correctly that way.

[Tidus_Beta]

i can completely confirm this is as a working method, theres a tool out there named wx360 (found in the usual, places) and for proof, i extracted the loading screen. heres a link:Here is the video.

if you dont beleive me, fine, but if u do it with a xbox1 game, and then run it in dademon or anything like that, it starts up the *this is a xbox disc* video, which means it acts like a normal disc, even tho its a image.

once again, beleive me or not, but there the video!

Okay, I am posting a problem dealing with this Dual Layer thing.  I can read the first layer of any game and extract the files and it works fine.  Now I was using Lord of the Rings: Return of the King and found this problem to be true.  So I made a DVD+R DL full of music.  I used this with the swap method instead and now I am watching the laser right now having problems heading back toward the inside of the disc.  Is this a problem with the way the DL DVD was written or because I used a +R?  Has anyone done a dual layer disc successflly and what did you use nad see?

Also, if the 360 DOES use PTP then I have done something wrong because it seems the drive is heading back toward the middle trying to read it's way in from the outside like in UTP.  It is possible I wrote the Data DVD with Nero using the wrong mode.  I will go back and see if there is any way to tell.

It sounds like the same way a DVD Video does.  There may be a special way the DVD needs burnt like you said.

[H2290]

Well, I just noticed that my read had some screwed up files and ended up being the exact same size as The Longest Yard which I used and that is probably not a good thing.  It did read from the outside in on the second layer and I think that might be the problem.

[Gobelet]

Why can't we use a DVD-DL disc filled with zeroes all the way to the end of the DVD, written in PTP? Speculation again.

[H2290]

  Used T2EE PTP disc and no good.  But I did do the swap and then look at the DiscInfo Tool in Nero and now it is showing this for COD2

Capacity:  7.73GB - taken from T2EE disc apparently
Layers:  2 - that's right
Version:  1
Track Path:  OTP - now this was PTP when I inserted the T2EE disc and now it has changed
Title:  XBOX 360

And using a PTP disc as the original I can not get it to go past 50%, but with an OTP as the starting disc I have got finished ISOs that just seem to have some junk files.  I think the XBOX360 discs are OTP due to this and the reporting from the Nero Tool.  Maybe the junk files I am seeing after the extraction are encrypted files or signatures of some sort.  

[DivyX]

Can you define better those junk files? size possible name etc...

[DivyX]

That is interesting. I cannot reproduce this my self now so could you be able to make anything out if you look inside one of the junk files? Obviously those junks could be something your drive can't read as it is now, thus producing those files but then again if they would be sectors that it can't read i would think the files would be full of zeroes, atleast they then wouldn't contain any random data imo. Please do little glimpse of whats inside of them ( generally inside of them ofcourse   ).
It could also be nero thing, or relation between the discs being used or some sort of security "stuff" or you name the rest.
Can hopefully look this issue also tomorrow ( friday ).

[H2290]

Okay, I meant they are definitely OTP if you read the above post.  I just used an OTP disk (The Aviator) and got a good read on PGR3 with solid files throughout.  Default.xex is there, unlike with COD2 and I've also got all audio and such from both layers.  Seems like a good rip to me.

The DVD drive is still having real problems at the very outer edge of the disk which I find quite interesting, maybe there is something out there.

Well, maybe I am all wrong.  This seemed like a good OTP copy but it appears all audio on Layer2 is clumped into one gigantic file and unreadable.  So, is it PTP?  Good question.

I'm agree with you, after many tests I think that Xbox DVDs are in OTP, but the first layer is smaller than the first layer of a 'normal' DVD. So when you are reading sectors at the end of the first layer, you should already be at the beginning of the second layer...

This is why you can see on the first layer a XDVDFS entry for the folder 'layer2' (in 'Game\Audio\Music'), but when you go to the address desribe by this entry, it's not in the good place. So there is a difference between the real second layer and the one you make with the hotswap method.
