detail information

To round off this review, we will run some advanced tests on the LG GSA-4167B. These tests are: 'Sheep Test", protected audio discs and some special disc tests.

The '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 found here.

In the screenshot below taken from CloneCD, we see the LG GSA-4167B supports everything.

The LG GSA-4167B supports DAO-RAW recording mode, which basically means, it can write uncorrected data and sub-channel data.

As we can see from the table the LG GSA-4167B is a 'Two Sheep Burner", but it however failed to write the Safedisc V2.90 and Sheep3 tests.

Copy protected Audio:

For our protected audio test, we used the Exact Audio Copy program. We inserted the protected audio discs and if the drive was able to recognize the disc we tried to extract the music tracks to the hard drive. First let us look at the discs we had available for this test: 

Celine Dion: A New Day Has Come; protected with key2audio version 3.

Herbert Gé¶nemeyer: Mensch - This disc is protected with Cactus Datashield 200.0.4 .3(build 12b)

And Michelle: Leben!; protected with Cactus Datashield 200.5.1.91 - 5.10.090.

Results:

DVD-RAM:

The LG GSA-4167B is a so-called Super Multi drive, meaning is also supports the DVD-RAM format.

This drive is one of few drives that also support the DVD-RAM format, lets us look at the recording side of the disc, and as you can see it got differences from the other DVD+R/W/R9 DL and DVD-R/W discs.

You could see a very fascinating pattern of darker spots, supposedly these spots are used for calibration while writing and reading.

A DVD-RAM's disc can be formatted in the following formats:

• FAT32
• UDF 1.02
• UDF 1.50
• UDF 2.00
• UDF 2.01
• UDF 2.50

By formatting a DVD-RAM disc with FAT32 it will act like a removable hard drive and all writing will be done in the 'background processes". Meaning you do not have to wait for it to finish - you can start or work with other applications while the DVD-RAM is working without noticing any 'hangs" or CPU slowdowns.

Lets us take a look at the media we are going to use in these tests:

As you can read above the Panasonic DVD-RAM 5x media is made by Hitachi Maxell Ltd. and the Panasonic DVD-RAM 3x media is made by Matsushita Electric Industrial CO. LTD.

But now the interesting part - writing and reading DVD-RAM media.

Panasonic DVD-RAM 5x without verification

Panasonic DVD-RAM 5x with verification

Panasonic DVD-RAM 3x without verification

Panasonic DVD-RAM 3x with verification

For those not familiar with DVD-RAM, you might think that something went wrong during the write process, when the verification option is turned on - since the 5x media was written at 2.36x and the 3x media written at 1.45x. But not to worry - that is pretty normal for DVD-RAM discs, the reason for the 'low" speed is - the drive constantly reads back the data after writing it to verify that it's written correctly. We can also call it a 'bullet proof" writing/verify technique - with no data loss/errors.

Another advantage with DVD-RAM is that the discs can be formatted/erased/written at over 100.000 times before it will/can cause/report any errors. Let's try to read back the 2 discs that we wrote:

Panasonic DVD-RAM 5x

Panasonic DVD-RAM 3x

As we can see from the pictures above, the 5x media was read back at 5x using the P-CAV technique and the 3x media at 3x using the CLV technique.

Since we have no equipment at the present time to perform any quality measuring tests with the DVD-RAM format it will be skipped, but on the other side it should not be necessary since the RAM writer - verifies the written data by default itself.

Overburning:

To test the overburning capabilities of the LG GSA-4167B, we used the over-burning test in Nero CD/DVD-Speed.

For this test we used an Infiniti Professional Compax 99min/900mb CD-R. (Thanks to Medea International (UK) for providing the disc).

The LG GSA-4167B reported an over-burning capacity of 96 Minutes and 4 Seconds.

To test if the LG GSA-4167B is capable to read 100 Min CD-Rs, we used a 100 minutes CD-R written with another drive:

As we can see for the picture above the LG GSA-4167B had no problems reading a 100 minutes CD-R.

This concludes our LG GSA-4167B review, lets head on to the last page to read our conclusion…
