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:

• Sony's Key2Audio from "Celine Dion - New Day Has Come"
• Cactus Data Shield 200 from "Natalie Imbruglia - White Lilies Island"

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 drive recognized up to the 13th Audio track of the CDS200 disc,

and with the "Retrieve Native TOC" option removed, the drive recognized the 14th track.

The test results are shown in the following table:

The BenQ DW1640 is capable of reading/ripping both Key2Audio and CDS200 protected discs.

• 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 which create problems 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 to 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 Audio CD+CD-Text. The burned media was checked for C1/C2 errors and for BETA/Jitter errors with PlexTools software using Plextor PX-716A (firmware v1.07).

 

• C1C2 Error rate from PleXWriter PX-716A (8X CLV reading speed)

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

The C1/C2 error graphs show that the 740A managed to produce a 100% error free disc.

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

No errors were reported after extracting all files. The drive can backup the disc 100% accurately.
