Lite-On SHW-1635S review

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 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 we see that the Lite-On SHW-1635S supports all available write and read features in CloneCD:

The Lite-On SHW-1635S supports DAO-RAW96 recording mode. This means that it can write uncorrected data and subchannel data.

Below are our results from the ‘Sheep Tests”:

The Lite-On SHW-1635S qualifies as a two sheep writer and could also backup Safedisc version up to 2.90 or maybe even higher.

Overburning:

To test the CD overburning capabilities of the Lite-On SHW-1635S we used the overburning test in Nero CD-DVD-Speed. According to Nero CD-DVD speed the drive can overburn to more than 99 minutes.

Media used is Ritek 99-minute media. We had problems with Nero and thus used the create data disc function in Nero CD-DVD Speed with overburning enabled and set to 99:57.74

Nero CD-DVD speed wrote the disc with no problems up to almost 100 minutes

There are no problems with reading the 99-minute disc.

Now, this is the end of the testing part of this review, head over to the summary and conclusion at the next page…
