To round off this review we will run some advanced tests on the ASUS DRW-1604P.
Copy protection:
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-1604P 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":
| Sheep Tests | Reader: |
| One Sheep Writer | Yes |
| Two Sheep Writer | No |
| Safedisc Writer | No |
| Three Sheep Writer | No |
The ASUS DRW-1604P qualifies as a one sheep writer. This indicates that it will have trouble copying discs protected with newer versions of Safedisc and other copy protection schemes.
Overburning:
To test the overburning capabilities of the ASUS DRW-1604P, we used the overburning test in Nero CD/DVD-Speed.
The maximum capacity that we could reach is 81:57.69 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.
This completes our ASUS DRW-1604P review, head on over to the last page and read our summary and conclusion…
DVD+R9 Double Layer Performance
The jitter tests in plextools with plextor drives and in CD-Speed with BenQ drives is not accurate enough. If we should believe benq reported jitter, 90% of the discs would be out of specs exceeding 9% jitter.

I hpe you present soon a review of the Asus 1608 or Pioneer 109
We previously reviewed the Pioneer [b]A08XLA[/b], which can be considered a different drive because it uses different hardware and different firmware.
Cdfreaks tries to review as many drives as possible.
Hope some new reviews are on the way
