Looking for help

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

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.

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

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)

Thanks for yours information again, RetroGamer.

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.

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.

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.

And also thanks for your information, pablogm123.

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.

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.

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).

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.

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

Thanks the useful information.

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.
