detail information

To round off this review we will run some advanced tests on the ASUS DRW-1608P.

The "sheep test":

For this test, we will use the Sheep tests made by Alexander Noé. Why is it called sheep test? That is because the symbol of the first 1 to 1 copy program named CloneCD is a sheep. When looking at supported writers, you will notice that the feature list has sheep to indicate if a feature is supported or not. In this case we are interested in the writer's ability to backup/write weak sectors. Also called: 'Correct EFM encoding of regular bit-patterns".

⋅        No sheep: Can't backup any safedisc 2 versions without the help of software tricks
⋅        1 Sheep: Can backup safedisc 2 up to version 2.4x without software tricks
⋅        2 Sheep: Can backup safedisc 2, including version 2.5x
⋅        3 Sheep: Can write all possible weak sectors, few if any writers could do this.

One of our forum moderators, Womble, has written a guide concerning the 'Sheep Test" that could be found here.

In the screenshot below we see that the ASUS DRW-1608P supports all available write and read features in CloneCD:

The ASUS DRW-1604P supports DAO-RAW96 recording mode. This means that the drive is able to write uncorrected data as well as subchannel data.

Below are our results from the 'Sheep Tests":

The ASUS DRW-1608P qualifies as a zero sheep writer. This indicates that it will have trouble copying discs protected with various versions of Safedisc as well as other copy protection schemes.

Overburning:

To test the overburning capabilities of the ASUS DRW-1608P, we used the overburning test in Nero CD/DVD-Speed.

The maximum capacity that we could reach is 82:10.27 when testing with an 80 minute Ritek CD-R. The drive may be able to overburn at a greater capacity when using other CD-R types that are more suited for overburning.
