Something wrong with C2 rereading again.

...
Reread times 50, ErrSectorNum 2/ 2
Reread times 51, ErrSectorNum 2/ 2
Reread times 52, ErrSectorNum 2/ 2
Reread times 53, ErrSectorNum 1/ 1
Reread times 54, ErrSectorNum 1/ 1
Reread times 55, ErrSectorNum 1/ 1
Reread times 56, ErrSectorNum 1/ 1
Reread times 57, ErrSectorNum 1/ 1
C2 error was fixed at all.

Creating descrambled file(LBA) 126723/126723
Creating bin, cue, ccd(Track) 3/ 3

And the data track has 52 unfixed errors according to cdmage (5 are not fixable). Have you changed anything in the rereading code?

Tested the override offset option successfully, many thanks.

You should to rewrite this text to explain the exact use of that option. By trial and error I have deduced that you have to enter the positive value (in samples) you want add to the standard offset correction, or the negative value you want to substract. For example, to applying +43 offset correction you have to enter +13 for a +30 drive.

Running discimagecreator.exe -rall g: 8 test.bin c2 750 over +13 I got this .dat:

This is D8 command for plextor. But This structure can't have a FUA flag.
I don't know where it has a FUA flag.

SecuROM (and probably Tages/Starforce) is pretty simple in that it uses twin sector's, aka duplicate sectors. The protection checks for these sectors using seeking techniques. We are unsure if it actually checks for the existence of the sectors, or creates a signature based on seek times. But I suppose that is not important, dumping the sectors is what is important here. Since plextor seems to be able to do so with D8, it's possible you may be able to develop a way to dump these discs reliably.

SafeDisc/SmartE/LaserLOK all use intentional C2 error, like Cactus Data Shield. No need to really worry about these ones, as it is not possible to read the data with any standard drive.

about SecuROM
Thanks info. I want to research for the future.

http://www.hydrogenaudio.org/forums/ind … opic=16188

Thanks info. I got CDparanoia src code.

Code: Select all

static int i_read_D8 (cdrom_drive *d, void *p, long begin, long sectors, unsigned char *sense){
  int ret;
  unsigned char cmd[12]={0xd8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};

  if(d->fua)
    cmd[1]=0x08;

  cmd[1]|=d->lun<<5;
  cmd[3] = (begin >> 16) & 0xFF;
  cmd[4] = (begin >> 8) & 0xFF;
  cmd[5] = begin & 0xFF;
  cmd[9] = sectors;
  if((ret=handle_scsi_cmd(d,cmd,12,0,sectors * CD_FRAMESIZE_RAW,'\177',1,sense)))
    return(ret);
  if(p)memcpy(p,d->private_data->sg_buffer,sectors*CD_FRAMESIZE_RAW);
  return(0);
}

umm.. this code, bit 3 of byte 1 (fua) is on. My tool is already same implementation.

As described in the MMC spec (http://www.t10.org/ftp/t10/drafts/mmc4/mmc4r02f.pdf),
READ_CD does not allow any FUA bit at all, so if this reading method is chosen then
flushing tricks are needed. However, other MMC commands like READ10 (0x28) and
READ12 (0xA8) support the FUA bit.

I know this pdf, and I know above. My tool call READ12 to reread.

Posted: **Sat Nov 02, 2013 10:42 pm**

Testing the tool. To dump discs in good condition (without E32 errors, the vast majority of my collection) works very nicely currently (but read below the exception).

I need to find a somewhat damaged audio disc which can produce E32 errors, but still recoverable by rereadings, to test properly the FUA code.

-----------------

Another suggestion, I have used these discs (in near mint condition) to test your tool:

https://redump.info/disc/21229/
https://redump.info/disc/21296/
https://redump.info/disc/27420/
https://redump.info/disc/29606/

Please, do not unscramble the scrambled data sectors of the pregaps of the audio tracks, like the previous releases of your tool used to do (even these PC Engine discs dumped by your tool could match in the past the DB without editing/patching anything, as outputted by your tool). Left as they are, even if they are marked as data at subcode level, because general track type overrides that.

-----------------

Latest suggestion for the future: it would be cool that you could implement a routine to verify "à la" CDmage if a given data track extracted contains corruption according to the ECC/EDC stored, and report that in the "_errorlog.txt" file or similar.

Yes, please don't unscramble data sectors in audio tracks.
