Topic: Looking for help

Hello, everyone. Sorry for many question.

I always get wrong hash audio-data when dump one-Data and one-Audio CD.

But no problem for multi-audio track CD via EAC using the same way.

This time I choose a [SS]Shining-Wisdom that have been verified by 4 dumpers.

I found there are two datas in DB, so I dump Track01.bin first and match that one. (lucky)

http://redump.org/disc/3235/  (The other one have different Track01.bin)

After calculate the exact offset manually, it's +684 ok. (And the ringcode is P2K, too.)

2nd question:

Another Game with one-Data and one-Audio, but it's PSX game.

http://redump.org/disc/9568/

Use the same way, and the Audio is match the DB.  (Wow!!)

but get a one-sector-error Track01.bin.

Re: Looking for help

Sorry everyone, the 1st question solved.

I use the write offset to read offset correction.

Maybe I should go to the bed and sleep more.

Re: Looking for help

so, everything solved by yourself? you're good boy wink

you are using a pioneer drive, they can't handle those special discs by sony.
cdmage reports a corrupted HEADER field, which is most likelly zeroed in your case!

Re: Looking for help

Hmm, I'll try it again after getting  the other devices.

Thank you, Administrator


Sorry, the last question:

Fill-up QSF on the last sector of Track01 will match the DB but still have 1 error.

Then clear the User Data will match the old history and no error occured.

If the situation happened again, should I fixed it? (Ex: SLPS-00451)

Re: Looking for help

I try to borrow one drive that support PR, today, and dump it via PR.

...

So the PR fixed it automatically.

And the 01.- cd.track.img match the newest DB, CRC32 = dab05773

http://redump.org/disc/9568/

The cdmage check result is "Image has 1 corrupted sector(s)."

Need fix or no ?  Confused...

Never fix a PSX image with CDmage! All the PSX NoEDC discs with audio tracks have always (at least) 1 corrupted sector!

Re: Looking for help

Thanks for yours answer, RetroGamer.

Best regard.

If the SLPS-00451~2 have the same case, shall I post "Error = 1"?

Re: Looking for help

Yes, check the images with CDmage and post the error count (Cdmage should be used only to check the number of corrupted sectors and never to fix them!). But beware, pionner drives can't dump this kind of discs correctly.

Re: Looking for help

That's why I ask the question, fix or not, because I only have the Pioneer devices so far.

Re: Looking for help

Well, I know the answer is "Do not use the Pioneer Drive to handle such special discs",

I just try to find a solution for some drive unsupport PR, that's all.


Thank everyone who give me useful information.

Re: Looking for help

I own a very similar Pioneer drive and audio trap disc method works flawlessly, without removing drive case. Also, PerfectRip runs fine, but only with pure CDDA discs.

Re: Looking for help

The Pioneer drives can't  set the sub-channel 001b mode in PerfectRip.

So dump by the Pioneer drives via PerfectRip always wrong CRC32.

That's why I answer the post below.

Re: Looking for help

Only true Plextors can use 100b (Packed mode). 001b is raw mode, pretty standard. Unfortunately, Pioneer drives cannot overread into lead-in (Needed for PF and mixed mode CDs).

Once you master audio trap disc method, it works very fine (No more data tracks screwed up by drive chipset's misinterpretations) and you won´t need a very expensive and hard to get true Plextor drive for properly dumping certain discs.

Re: Looking for help

You're right, in fact I have another Pioneer DVD-129P can over-read the Lead-in zone.

My motherboard support only 1 IDE socket, exchange the drives needs to restart the OS. (lazy...)

So I usually use the DVR-111 to dump, it works fine on Sega Saturn CD.

The special dump-guide device almost old model and hard to find unfortunately.

Anyway thanks, I'll try the audio trap disc method.

Re: Looking for help

DVD-129P is Mediatek based (+6 in AccurateRip). If that drive can overread into lead-in and lead-out, it is suitable for PF.   You can use IsoBuster's sector viewer for testing:
-If you can go to negative LBA such as, -1, -2 (Until -150/-149, more or less)... drive can overread into lead-in.
-If you can go past last LBA of disc, until a certain ammount of sectors, drive can overread into lead-out.

And Retrogamer is right. I have lots of PSXs discs which I cannot dump (I speak of data track, not audio tracks) properly with my Pioneer DVD writer, NEC based, because of last sector. The only drive I own which doesn´t screw up last sector is my Panasonic/Matshita SR-8586B (VOS based).

Re: Looking for help

I use the EAC to test Pioneer DVD-129P, it shows overread Lead-in only.

Because I dump Saturn Game often, so the DVD-129P take a vacation. lol

Ok, I'll exchange the one next time to test its overread Lead-out by Isobuster.

Thanks the useful information.

Re: Looking for help

A drive can overread in EAC, but not in IsoBuster/PF, and viceversa. I guess EAC uses a distint method for overread. For examble, my LH-20A1P can overread into lead-in/out in PF/IsoBuster/dbPowerAMP/CDTool/Nero CD Speed's test, but not in EAC. Whereas my GCE-8526B can overread into lead-in/out only in EAC.

Overread into Lead-in may be useful for discs with negative combined offset.

Re: Looking for help

Oh, you mean the drive read-feature is application depend, not it's native right?

I guess maybe read command or ASPI(SPTI) layer different.

After I test the Pioneer DVD-129P via EAC and PR and Isobuster, I'll show the report here.

Best regard.

Re: Looking for help

I use Pioneer DVD-129P via PR to dump SLPS-00917

http://redump.org/disc/9568/

And it get a perfect Track 01 and match the DB, but it hang up when jump to Track 02.

I restart PR and lost the drive, it shows blank on  devices screen.

Maybe my chipset problem, I'll change it to another PC.

Report continue.........Log out.

Re: Looking for help

After move to 2nd PC(same ASPI and SPTI), the result is stop at the last sector of Disc.

The Track 01 also wrong CRC32. (But I don't know why.)

Isobuster test result is overread Lead-in only.

That's all.


PS: Audio trap dsc + CDRWin method get the wrong Track01, too. (Fix by cut the offset)

24 (edited by axisleon 2012-01-19 22:38:31)

Re: Looking for help

If the PR set length per read command to burst, not 1 sector.

It will get the right CRC Track01(data), but still stop at the last sector of Disc. (Track02 will be delete after U stop PR)

Maybe it can use PR(data) + EAC(audio) method to match the DB. ( hmm nonsense)

Re: Looking for help

If your drive has a correction offset value of +6 and factory write offset is +2, combined correction offset is +8, 32 bytes (You can, pottentially, miss 8 bytes at the end, not beggining, of disc). Thus, if you use audio trap disc, you can extract 0 - 50197 range using CDTool (With C2 reporting enabled, subchannel reading (Raw mode and deinterleaving enabled) and Main+Sub+C2 read order). You have to substract 32 bytes at the beginning of dump and append 32 zeroed bytes in the end. Start of a data track scrambled is always 00 FF FF FF FF FF FF FF FF FF FF 00 01 82 00. (00 FF FF FF FF FF FF FF FF FF FF 00 02 00 00 once descrambled).

Then, open SubCode Analyzer, load .sub and make CUE file. This CUE file is useful for spliting dump with CDMage and, then, descramble data track. If everything is fine (Tracks properly cutted, no missing data...), you will get a match. With trap disc method and my Pioneer drive I have dumped several discs for my personal archive and they match database.

Every utility noted is here:
http://forum.redump.org/topic/5272/tools-of-the-trade/

PS: As far I know, also IsoBuster extracts ranges in burst mode, not single sector mode.
