Sheep Test

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 can be and be found here.

In the screenshot below taken from CloneCD, we see the Samsung SN-S082M supports everything.

The SN-S082M supports DAO-RAW96 recording mode, which basically means, it can write uncorrected data and sub-channel data.

As we can see from the table and screenshots, the SN-S082M is a “Two Sheep Burner”. It also succeeded in writing the Safedisc V2.90 test but failed the Sheep3 test.

Overburning

CD-R overburning:

To test the overburning capabilities of the Samsung SN-S082M, we used the over-burning test in Nero CD/DVD-Speed.

Nero CD/DVD Speed reports that the disc can be overburned to 96 minutes and 36 seconds.

To test if the Lite-On LH20A1P is able to read overburned CD-Rs, we have set up a compilation in Nero and burned the disc, which has been tested above, to its maximum capacity and tried to read back the disc:

The Samsung SN-S082M wrote the disc with 24x speed in 5minutes and 46 seconds.

We read the disc back in CD-Speed at full speed. As we can see above, the Samsung SN-S082M had no problems in reading the disc to the end, with a maximum read speed of 26.82x.

DVD+R overburning:

First we tried to overburn a DVD+R disc.

As we can see above, the Samsung SN-S082M does not support overburning on DVD+R media.

DVD-R overburning:

Now we try a DVD-R.

As expected, the drive does also not support overburning on this media type.
