You can dump it directly with IsoBuster, of course.

By the way, I remember Hitachi-LG drives with Renesas chip (The ones with +667 in Accuraterip database) can extract such last sector without neeeding workarounds.

One can use psxt001z to fix and injector to "unfix" the sector. That matches then what you get when you extract the data track with CDTool and "ECC off" checked.

I learned a lot, thank you, pablogm123.

By the way, how about the anomaly PS game with Mode1 data mixed in Mode2 data area.

Any clue? Ex: SLPS-01565 and SLPS-02814. Dump with Isobuster directly? (Single Data Track Game)

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:

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

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)

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)

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.

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.

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.

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.

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).

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.

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.
