TY +R 16x @ 8x
Perfect TRT.

ritek 48x cd-r burned at 24x with burrrn, i also add a liteon scan:bigsmile:.

i am currently using a “LG GH20NS15”, well some of my Transfer Rate Tests seems weird, so could anyone tell me if these screenshots are alright.

Data disc [SONY 16D1] burned at 16x using a “LG GSA-4167B”,
while the Transfer Rate Test were done using a “LG GSA-4167B” [refer to pic03],
and the Transfer Rate Test were done using a “LG GH20NS15” [refer to pic04].

while the Transfer Rate Test were done using a “LG GSA-4167B” [refer to pic05],
and the Transfer Rate Test were done using a “LG GH20NS15” [refer to pic06].

The highest speed the “LG GH20NS15” can reach of a data disc [SONY 16D1] during a Transfer Rate Test is at “13.05x” .








#605

Maybe write quality with the LG GSA-4167B was not good at the end of the DVD-R, so that it is not reasy to read.


#606

The first graph is a Create Data Disc Test, and is not considered to be the normal TRT [which is reading an already written disc]. That’s normal.

None of the TRTs look right. Try burning a disc at 8x in the newer LG, and then do TRTs on both drives, please. :slight_smile:

Verbatim -R 16x @ 20x
Very strange Jitter, but the disc plays fine.

Data disc [SONY 16D1] burned at 16x using a “LG GSA-4167B”,
while the Transfer Rate Test were done using a “LG GSA-4167B” [refer to pic03],
and the Transfer Rate Test were done using a “LG GH20NS15” [refer to pic04].

Data disc [SONY 16D1] burned at 16x using a “LG GH20NS15”,
while the Transfer Rate Test were done using a “LG GSA-4167B” [refer to pic05],
and the Transfer Rate Test were done using a “LG GH20NS15” [refer to pic06].

Refer to my last post for the pictures.

Well the thing is if the disc that i burned using the “LG GH20NS15” shows an odd Transfer Rate Test with this drive, why would the “LG GSA-4167B” show a proper graph.

And why does a disc that is burned using a “LG GSA-4167B” shows a proper Transfer Rate Test with this drive, while the “LG GH20NS15” would show an odd graph.

So it then seems that both drives are capable of burning a disc, but the big question is why does the “LG GH20NS15” not show a proper graph. Also both drives give a “100% Good, 0% Damaged, 0% Bad” for the disc that was burned dring the “ScanDisc” test.

Anyway i will try burning a data disc [SONY 16D1] at 8x, and check out the graphs on both drives.

And could there be a chance that the dvd-writer may be defective. I bought it about 3 weeks ago.


#610

Both drives show an issue when reading the SONY16D1 discs written at 16x, and I would more than bet that it’s just a set of bad burns more than defective drives. There may be other issues, but we can figure that out after seeing if the 8x burns can be read back any better. :slight_smile:

and the Transfer Rate Test for this burned disc is done using a “LG GH20NS15”. [refer to pic04]

The ScanDisc test for this burned disc gives “100% Good, 0% Damaged, 0% Bad”.

Nero DiscSpeed v4.11.4.0 was used for the burning and Transfer Rate Test.






#612

Can you do a burst rate test and post the result?


#613

Here’s a complete Benchmark test for the above Data disc [SONY16D1] that was burned at 8x.

Refer to my previous post for additional pictures.

Nero DiscSpeed v4.11.4.0 was used for the benchmarking.

I remember reading that alcohol and daemon tools can mess the reading, so if you have them installed, try to remove them and see if that helps.

Read this.

Here’s a couple of benchmarks of a Data disc [SONY16D1] that was burned at 8x.

Complete benchmark with DAEMON Tools Lite v4.30.1 (SPTD v1.56) installed.
Refer to pic01.


Complete benchmark with “DAEMON Tools Lite v4.30.1” uninstalled and “SPTD v1.56” uninstalled.
Refer to pic02.

Here you can see that the transfer graph is perfect with SPTD uninstalled.
Also notice that the CPU usage is not so high.
Also the Burst Rate is normal.

Complete benchmark with DAEMON Tools Lite v4.30.1 (SPTD v1.56) re-installed.
Refer to pic03.

Here you can see that the problem comes back again with SPTD installed.
CPU usage is high again while the Burst Rate is quite low.

Guys, I just recently bought a DVD burner, its LG GH20 Super Multi DVD Rewriter. And when I was installing it I found out that its connected by SATA (Serial ATA), the problem is the cables in my system unit are all Parallel ATA.
Is there a way to connect this to my computer? by a adapter maybe? or should I return it to the shop and ask for some other model?

Please help.

Here’s my LG DVD Drive:

Here’s the back of the DVD Drive:

And here’s the cable (Parallel ATA) that my System unit has:

Please help.

Thanks guys!

:iagree: my first thought.

Oh so there’s nothing I can do about the SATA to Parallel ATA Cable thingy…

Anyways thanks, hopefully I can get it replaced.

I think that there are some sata to usb connectors, but i haven’t try any of this toys, theres also another way, much better imho, get a sata pci card.
