Comes both with or without rings. A bug in the Plextor firmware means any dump of either version made using a Plextor and any tool is likely to be bad. Incorrectly reporting the total number of errors.

For example, when dumping http://redump.org/disc/53929/ with ringless Copylok using either DIC or redumper and a Plextor drive, the error count is incorrectly reported as 1516, exactly double the correct 758 errors.

An incorrect _c2Error log looks as follows:
LBA[002312, 0x00908] Detected C2 error 380 bit
LBA[002313, 0x00909] Detected C2 error 20 bit

A correct _c2Error log looks as follows:
LBA[002312, 0x00908] Detected C2 error 300 bit
LBA[002322, 0x00912] Detected C2 error 300 bit

These discs can be correctly dumped using a non-Plextor drive and any of the following tools:

  • DIC (using an ASUS or compatible firmware drive)
  • redumper (Same as above)

Ringed Copylok meanwhile is supposed to have double errors (for example http://redump.org/disc/107930/). A correct Redumper dump of these will look like this.
[LBA: 2316] C2 error (bits: 1354)
[LBA: 2317] C2 error (bits: 1022)

Only a handfull of drives are known to be able of handling this variation of the DRM. Most, including Plextor and Redump compatible Asus drives will instead have these kind of errors in their logs.
