I am pretty sure that it's a fault of DIC handling transfers via USB/IEEE-1394, at least with certain enclosures. CDTool, PerfectRip and the «unnameable» works nicely with my PX-W4824TU, and this drive is just an externalized PX-W4824TA.

How many value is "MaximumTransferLength" of PX-W4824TA/PX-W4824TU?
My drive(PX-755SA) is 00010000(65536) bytes.
Please paste drivelog of STORAGE ADAPTER DESCRIPTOR.

it seems that DiscImageCreator doesn't detect PregapMode (ccd value) and always sets it to '0', even though many discs have a different value there..

I have recognized it and want to fix it. But I don't know about "PregapMode" and "PregapSubC", "DataTracksScrambled" in detail. Therefore, I always sets it to '0'.

Thank you.
And, in case of Plextor drive, is c2 bit order (msb points to 1st byte of main) or (lsb points to 1st byte of main) ?

C2 switch for GD-ROM ripping does work now, but unfortunately the dumped .sub is invalid (contains non-sense data). Without C2 switch the .sub is valid and the extra frame is no longer present. Anyway, the actual dump (with/without C2 error reporting) matches the expected.

fixed

The same one for main channel / 8, because there are 2352 bytes for main channel and 294 bytes (one bit per byte of main channel) for C2 pointers. And this way will proceed PF if you enter 0 as c2 read offset correction bit(s).

In case of Plextor drive, how many is the values of c2 read offset correction bit(s)?

My current wishlist:

-An option (for the -rall and -rgd modes) so that the C2 pointers are used only for purely informative purporses, without absolutely re-reads, like the old PerfectRip does. I mean the program will read and dump into a .c2/.c2e file the raw C2 pointers provided by the drive, but won't re-read anything marked as bad by the C2 pointers. This way I will know if a rip is good (no further action required) or bad: to resurface and clean the CD until getting 0 C2 errors, to try another drive, to try another read speeds or simply replace the CD if nothing works to get a flawless dump without re-reads. Of course, the log file should report if the dump was flawless or not flawless.

-The suggestion posted above applied to the -ra mode as well. And I would like that you could implement offset correction for the -ra mode: it would apply, as default option, the standard one defined by the AccurateRip database plus the possibilty of override it via the add parameter implemented in the -rall mode.

http://www.mediafire.com/download/u0olo2c51f2qv13/
coded.

By the way, do you know the offset of the C2 error in detail?
In case of perfectrip, it can set "c2 read offset correction bit(s)"

The possibility to set different read speeds for the initial read and the readings. For example, initial read at 24x speed and re-reads at 4x speed.

I coded it. c2 option val3.

Rewrite the -ra module so this tool can act as a CDTool replacement to dump as audio (D8 or audio trap disc) any range that the user desires with subcode and C2 error reporting (outputting both as .sub and .c2e files), adding the possibility to correct the offset (with the possibility to override the standard one). This module should support Plextor and non-Plextor drives and could be useful to dump the high density of DC games.
If a Plextor drive is used, D8 command and order is Main+C2+Sub.

improved ripping GD-ROM
  added "-rgd" command for HD area (integrated "-ra", "-dec", "-split")
  c2 error option don't test. (Because my drive(TS-H352C) don't support C2 error report.)

If a non-Plextor drive is used, BE command and autodetect if the drive uses Main+C2+Sub (NEC based for example) or Main+Sub+C2 (Mediatek bases for example).

I don't support it yet.

umm.. I don't fix about this.

reported all the errors were fixed, but cdmage shows 2 errors in the data track. There's a bug in c2 reporting/fixing somewhere.

Depending on a drive, it's possible that it don't report C2 error exactly.
Therefore, in this tool, multiple read a non C2 error sector (at present 2 times)
If necessary, I can change a reading times.

At present, it can fix the "4096" C2 error.
I can increase this values if I can allocate memory.

Thanks info. I got CDparanoia src code.

  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.
