Unlicensed PS2 disc has intentional C2 errors like safedisc. Safedisc has sync + msf + mode but unlicensed PS2 disc hasn't it.

LBA[000026, 0x0001a]: Track[01]: Invalid sync. Skip descrambling

Some people discussed how to handle intentional C2 errors. Please confirm them how we should do it.

Half scrambled. Perhaps Mastering error.

swap mode continues to read until the 1st 0xaa appears. It seems 1st 0xaa is 77402 sector.

Last sector is 77400.

DIC overreads 1 sector due to this problem.

As I understand from the wiki, there's no way to get these infos (or create an IRD with redump2ird (D1/D2)) with this dumping method, or am I missing something?

Yes, you need to get PS3 drive to get the disc key/id. If you get the drive and 3k3y ripper, you can get these info easily, using my authentication tool. http://forum.redump.org/topic/22897/ps3 … tion-tool/

Only 1 sector is overread if combined offset is plus, so offset +588 or more has not supported yet.

Can you tell us how the descrambling works again? I mean, for mastering errors, what are the criteria to descramble?

1. Sector needs to be the data [Ctrl byte of subQ is 4 or 6]
2. Sync needs to be valid [00 FF FF FF FF FF FF FF FF FF FF 00]
3-1. If mode is 0x60, 2336 bytes need to be zero.
3-2. If mode is 0x61 and reserved area (from 0x814 to 0x81b) is reversed (all zero), it's descrambled.
3-3. If mode is reversed (0x00 or 0x01 or 0x02), it's descrambled.
3-4. If mode is unknown and msf is reversed and reserved area isn't all zero, it's not descrambled.
3-5. If mode is unknown and msf isn't reversed and reserved area is all zero, it's descrambled.
3-6. If mode is unknown and msf isn't reversed and reserved area is invalid, it's not descrambled.

I guess the only reason for these manual fixes was to get a "proper" sync/msf/mode to fill it with 0x55?
So if these sectors are no longer replaced with 0x55, the code is obsolete and can be removed?

And are unreadable sectors (e.g. ring protection) replaced with 0x00, not 0x55?

They are still 0x55 when inside a data track (they normally have C2 errors)

OK. And I have another question.
The sector of VOB protection with "00 FF 00 FF 00 FF 00 FF  00 FF 00 FF 00 FF 00 FF" should be handled as data sector to be descrambled?

we decided that only protection sectors with C2 errors should be replaced with 0x55 (and a proper sync/header with the same mode as the track).

Good. I'd waited this.

SafeDisc dumps are unaffected, but some other protections (mainly SmartE, CD.IDX, VOB ProtectCD, 3PLock) will need to be rechecked/redumped.

Codelock and Unlicensed PS2 disc (DATEL) have several intentional C2 errors like SafeDisc.

SmartE has the duplicated MSF. DIC is fixing manually like this.

VOB ProtectCD has invalid sync/msf/mode. DIC is fixing manually like this.

I tried it.

2. Set and send command {0xf1, 0x06, 0, 0, 0, 0, 0, 0, 0x0b, 00}
3. Returned error [Key-Asc-Ascq: 05-24-00 = ILLEGAL_REQUEST - INVALID FIELD IN CDB]

It is possible to read into the lead-out (~13 sectors or so) on the same Blu-Ray Drives that support BEh (READ CD) with the CD-DA flag by using the vendor command to read into the cache. The command is as follows:

Which vendor supports this command? Where did you get this info? Is there a specification like ecma, t10.org etc?

It doesn't look on these patterns as c2 errors.

These are not mastering errors that I want to skip, they are perfectly valid sectors.

Yes, but your disc is single data track. There is no merit to use DIC.

The outer areas of the disc need slower speed to not get read errors when they are "over burned" size. I have to stop a dump and redump with slower speed to avoid C2 errors on some discs.

Then, you should use the slow speed from the beginning when dump the over burned disc.
Or if DIC can detect it is the overburned disc, DIC can set the slow speed forcibly.

Is there any chance of slowing down the drive on read errors automatically?

Why? I don't think slow reading generates good reading. If you think slow reading is good, you need to specify that.

Well I looked at the sectors in cdmage, on one disc the sync is shifted by 16 bytes to the right (safedisc) and on another disc the sync is shifted into the previous sector's ecc/edc area (normal disc). So yeah I think this is a bug with the DVD drives.

I think so, too.

No. RingPROTECH / ProRing have always protect.pro. This file occupies the size about 40MB.

Another issue, I don't know if it's the DVD drives or a bug in DIC. There is no C2 errors but some sectors are corrupted after unscrambling. Here is the log of the latest one I had this happen. This only happens with my 716 and 760, it does not happen with any of the CD drives.

Some dumpers also have reported this. I've thought this is the problem of drives.

If you have time, please test below.
1. Dump your disc using cdtoimg.exe (d8 hacked) and descramble using Descramble_CDDA.exe.

If I remember right, cdtoimg uses the submode 00 (only main-channel is dumped). If Descramble_CDDA can descramble all sectors with no errors, I think the submode 08 (main+c2+sub) of DVD drive have bug.
