To round off this review we will run some advanced tests on the LG GSA-5163D.
The 'Sheep test":
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 LG GSA-5163D supports all available write and read features in CloneCD:

The LG GSA-5163D 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 LG GSA-5163D qualifies as a two sheep writer but can't produce functional backups of Safedisc 2.90 protected discs. This makes the LG an average choice for backing up protected games.
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:

Westlife: World of our own is protected with Cactus data shield 100.
Natalie Imbruglias White Lilies Island. This disc is protected with Cactus Datashield 200

Shakira: Laundry Service, which is protected with Key2Audio version 2.

And finally Celine Dion: A New Day Has Come, that is protected with Key2audio version 3

The LG GSA-5163D did not have any problems with reading the protected audio discs.
DVD-RAM:
The LG GSA-5163D is a so-called Super Multi drive, which means it also supports the DVD-RAM format.
Lets look at the recording side of the DVD-RAM disc and as you can see, there are 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:


Maxell branded DVD-RAM media certified for 5x. (Thanks to LG Korea for providing it).

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

For those who are not familiar with DVD-RAM would probably think that something went wrong during the write process since the 5x media was written at 2.35x. But don't worry - that is normal for the DVD-RAM format, the reason for the 'low" speed is that the drive constantly reads back the data after writing it, to verify that it's written correctly. We could call it a 'bullet proof" writing/verifying 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 disc that we wrote:

As we can see from the pictures above, the disc was read back at 5x using the P-CAV 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-5163D we used the overburning test in Nero CD/DVD-Speed. According to Nero CD/DVD speed the drive can overburn to about 95 minutes:
Media used is Ritek 99 minutes media. And we also wrote a 94 minute disc in Nero:

Unfortunately, the drive could not write to more than 95 minutes, but what about reading 99 minute discs?
There are no problems reading the 99 minute test disc.
Now, that concludes our LG GSA-5163D review, head on to the last page to read our conclusion…







Great writer and a great review.
If LG make better firmware-support the LG-drives should be the absolute best


The GSA-5163D is also optimized for working in an external enclosure. Take an GSA-4163B and put in the same case - I doubt you will be able to reach 16x at USB at least. 16x on firewire may work.
This is because LG have optimized the GSA-5163D firmware to work at max with this enclosure. And to be honest - this is the first drive I've had that actually reach REAL 16x speed on USB2 - regardless of drive and enclosure (yeah I have lik 5-6 different enclosures).
All respect to LG for really testing that transfer rates could be reached like expected - unlike Samsung ang NU with their external writers which can only reach around 13-14x before slowing down. Very dissapointed that NU and Samsung is marketing 16x external drives that can't reach 16x.
So yes - in my eyes it's worth it - buying this drive brings you a drive that is fully tested at both USB and firewire - I did not have a single problem with USB or Firewire while testing.
Buying a drive x + enclosure x will in most cases lead to problems in a way or another.


Before I retun it to Samx Club, how did you get the firmware upgraded to A103? I only see firmware upgrades for the internal model on LG's US website, and this version can not recognize my external drive, thus, preventing any attempt at upgrading the firmware..



GSA-5163D fw A103.
Tried the drive on USB2?
