I believe Jackal is referring to this topic. That CloneCD method won't work, though, it just prevents EAC from showing a sync error in the overread sectors. That doesn't mean it can actually access any data in the overread sectors. If you are lucky you'll get a match, but only in case the overread sectors are all 00s. Therefore, you can never really be sure whether you've lost any data!

However, that IsoBuster method proposed by velocity37 might actually work. I didn't try it yet but it does sound promising for drives that support it. It's still quite intricate so you should rather buy a decent drive. A Plextor PX-716A is usually quite cheap here on eBay.

Hi Ghazy, yes, it's a bit hard to find here I found only 2 German online shops... the first one wants more than 10€ for shipping and minimum order is 20€ so you'd have to buy 4 bottles -.-

The second one looks much better, "only" 5€ for shipping and no minimum order. I'm thinking about ordering one or two bottles there myself

Normally from the inside out. When locating scratches you'll have to consider that the amount of data per rotation gets bigger and bigger towards the outer edge of the disc. Therefore, assuming the read error occurs at 50% of the extraction, the scratch isn't exactly at the middle of the disc but quite a bit nearer to the outer edge.

The amount of disk space needed to store the byte positions' numbers would be even bigger than the actual uncompressed file Let alone the fact that Windows would pad these 1-byte files to 4096 bytes (?) anyway (edit: Granted, not if you compressed the files afterwards ^^). If this worked, even the biggest files could be compressed to a few KB, which is physically impossible. Forget it, random stuff like that is nearly uncompressible.

As much as I'd like to see Xbox dumping on the PC become reality, I voted YES. If the data can be dumped, it should be dumped, regardless of the inconvenience this brings. We don't accept scrubbed Wii/GC isos either, do we?

On the other hand, one could argue that all that counts is the game, not its medial embodiment. Then again, we spend so much time on things like correct gap detection, offset shifting, things that don't contribute to the gaming experience at all. We extract PC games as accurate as possible despite not even being able to play them (SecuROM etc.).

If there is a reliable way to extract the data inside these sectors it should be done.

Belated reply, I know, but hopefully still interesting...

According to my sources, the PS3's copy protection schemes have not really been cracked (yet!). It is possible to create disc images directly on the PS3 -- PC Bluray drives supposedly fail to recognize the discs. This works via Linux, albeit only on the old, fat PS3 as installing Linux on the slim PS3 is not possible anymore.

A simple dd if=/dev/cdrom of=/image.bin dumps the Bluray to HDD. The image can be burned to a BD-R but the PS3 does not read it, of course. Therefore, as far as I know this is currently only interesting in terms of preservation. I don't know if this method extracts the ROM mark (I strongly doubt it), which doesn't really matter as the ROM mark cannot be burned to a BD-R anyway.

Bluray movies can be dumped the same way on the PS3, by the way. They need to be decrypted via AnyDVD in order to be watched, though. This is also possible through a normal PC Bluray drive so you needn't really use the PS3 for this.

All in all, the PS3's copy protection mechanisms have worked remarkably well so far. It wasn't until this year that an exploit compromising the hypervisor was discovered -- it's still doubtful if this helps playing burned games in the long term. It can probably be patched away easily by Sony.

Hi devcon,

you can search for drives based on your criteria here: http://daefeatures.co.uk/search.php.

I recommend setting Accurate Stream to 'Yes' and Overread to 'Lead Out' or 'Both'. You'll get a huge list of drives from different manufacturers then which are principally suited for PSX (and most other systems) dumping. Even though this database maybe doesn't feature the newest drives you should definitely be able to find most of those on eBay for a very low price.

Yes I do, I'll have a look. By visible partition you mean the partition you see when you put a disc in a non-compatible drive, right? The partition with VIDEO_TS, AUDIO_TS and the system update?

I actually have written a "guide" (or rather some crude instructions ) and sent it to several people via PM. I'm reluctant to put it here publicly... You know how much trouble this can cause in our beautiful country -.-

One question that remains is how to distinguish WAVE3 from WAVE4. Supposedly there's also a WAVE5 (with Left4Dead 2 being the first game to use it). Do you by chance have any further information?

You probably haven't replaced the garbage sectors... Try to extract the game again and replace the byte range from 223182848 to 231571456 with 00s in a hex editor for WAVE2/3/4 and WAVE1 (108976-113071) dumps (see the Comments section of the dump to find out which WAVE the disc is). In case of WAVE1 (18128-22223) dumps, replace 37126144 to 45514752. You should get a match then.

If you have further questions or want to dump games that aren't in the DB already I can send you further instructions.

Oh cool, I didn't know that. Do you know what sets these drives apart so they can read these discs?
