To round off this review we will run some advanced tests on the Memorex DVD+/-RWN16 D2.
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 Memorex DVD+/-RWN16 D2 supports all available write and read features in CloneCD:
The Memorex DVD+/-RWN16 D2 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 Memorex DVD+/-RWN16 D2 qualifies as a one sheep writer, it cannot copy discs protected with Safedisc ver 2.51 and above. This means that this drive will have trouble backing up some copy-protected CD-ROM discs.
Overburning:
To test the overburning capabilities of the Memorex DVD+/-RWN16 D2, we used the overburning test in Nero CD/DVD-Speed.
The maximum capacity that we could reach is 92:57.74 when testing with an 80 minute Ritek CD-R. All attempts with a larger specified capacity resulted in a failure during the overburn testing process.
Mini DVD-R/RW:
To test the mini DVD-R/RW capabilities of the Memorex DVD+/-RWN16 D2, we burned one Memorex mini DVD-R 8cm and one Verbatim mini DVD-RW 8cm.
Memorex 4x Mini DVD-R
Verbatim 2x Mini DVD-RW
The Memorex DVD+/-RWN16 D2 was able to complete the burn process on both disc types with no issues.

This completes our review, head on to the last page to read our conclusion…
DVD+R9 DL Writing Performance
I'm sure users that have the drive will appreciate the review!
In addition, users that have the 1673S version (which uses the same enclosure) can benefit from viewing the USB2 and Firewire bridge limitations that I have detailed in this review.
Called their "technical support" and got some guy in the Phillipines blaming windoz XP updates.
I'm taking it back to my vendor, getting a credit and buying a Plexitor
