To round off this review, we will run some advanced tests on the Matshita DVD-RAM SW-9585. We will perform the Sheep Tests and Over-burn testing.
Advanced Tests
Copy protected data discs:
For this test, we will use the Sheep tests made by Alexander Noé. Why is it called sheep test? That's because the logo of the first 1 to 1 copy program called 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 taken from CloneCD v5.1.0.0, we see the Matshita DVD-RAM SW-9585 supports everything except RAW-DAO.
The drives used to verify that the tests work were the BenQ DW1640 and the Matshita DVD-RAM SW-9585 itself. Below are our results from the 'Sheep Tests":
| Sheep Tests | Reader: |
| One Sheep Burner | Yes |
| Two Sheep Burner | Yes |
| Safedisc v2.90 | Yes |
| Three Sheep Burner | No |
The test shows the Matshita DVD-RAM SW-9585 qualifies as a 'two sheep" writer. Very nice!
CD-R Overburning:
To test the overburning capabilities of the Matshita DVD-RAM SW-9585, we used the over-burning test in Nero CD/DVD-Speed.
The simulation showed that the drive can overburn the maximum capacity, which is 99:57.74.
We then used Nero CD-DVD Speed over-burn setting to see if we could actually write 99:57:74 to the disc. We used a Ritek 99 minute CD-R for this test. Thanks to Ritek USA for providing.
The MATSHITA DVD-RAM SW-9585 was able to burn the full 99 minute CD-R at 8x without any problems. Now we'll try to read the disc back.
No problems at all! Writing and reading 99 minute CD-R works perfectly!
DVD Overburning:
To test the over-burning capabilities of the Matshita DVD-RAM SW-9585 with DVD+R, we used the over-burning test in Nero CD/DVD-Speed.
The test indicates that DVD+R media cannot be over-burned with the Matshita DVD-RAM SW-9585.
Now let's try some DVD-R.
The test indicates that DVD-R media cannot be over-burned with the Matshita DVD-RAM SW-9585.
We set the over-burn setting in CD-DVD Speed to 4500 MB so we could try actually writing some discs.
DVD+R result.
DVD-R result.
To sum it up: The drive can overburn CD-R media up to the full 99 minutes at 8x writing speed. Reading 99 minute CD-R is also no problem. DVD±R over-burning is not supported on the Matshita DVD-RAM SW-9585.
This concludes our Matshita DVD-RAM SW-9585 review, head on to the last page to read our conclusion…
DVD+R9 DL Writing performance
" Unique Disc Identifier : [DVD+R-DL-RITEK-D01-001] "
in Ritek and Ricoh and 
for the Optodisc ram
Looks like overall bad burner to me. I'm not buying something like that, looks like the burn ZCLV is slow too.
Ritek are bad, full stop!
