For the test procedure, we used three audio discs with different audio copy protections. The ripping process on all protected Audio discs was carried out with Exact Audio Copy v0.9 beta5.

The tested protected Audio discs were:

The Cactus Data Shield 200, contains artificial errors that are not easily bypassed by the reader, while the Key2Audio contains a second session causing problems for readers when trying to read the Table Of Contents (TOC).

The LG drive recognized up to the 12th Audio track of CDS200 disc,

and with the "Retrieve Native TOC" option removed, the 13th Data track was also recognized.

The test results are shown in the following table:

With Key2Audio discs, EAC didn't report any timing problems and at the same time, Read&Test CRC check comparison was the same for corresponding tracks. The drive could not rip 100% accurately the CD200 disc where Read&Test CRC check comparison was not the same for corresponding tracks.

- Cactus Data Shield 200.0.4 - 3.0 build 16a (Aiko Katsukino - The Love Letter)

This is a "special" CDS200 build, since it doesn't contain any artificial errors during the ripping process. Most problems occur when trying to write the ripped wav files, since the produced CD-R disc contains C2 and CU errors! This "problem" is rumored to be connected with specific chipset weaknesses.

We ripped the disc contents with EAC and burned the wav file produced from the Cactus Data Shield 200.0.4 - 3.0 build 16a disc with the latest Nero version as AudioCD+CD-Text. The burned media was checked for C1/C2 errors and for BETA/Jitter errors with PlexTools software using Plextor PX-716A.

- C1C2 Error rate from PleXWriter PX-712A (8X CLV reading speed)

- BETA/Jitter Error rate from PleXWriter PX-716A

As it can be clearly seen from the C1/C2 Plextools graph, the drive did not manage to produce a 100% error free disc, due to the C2 spike reported near the end of reading.

We then tried to extract all wav files with the Plextor PX-716A and PlexTools DAE Error Correction 5th Level enabled:

No reading errors were reported after extracting all files.
