In order to test the writing quality and readability of the burned media we are used two readers with two software applications: CD writing quality according to Plextools is very much dependent on the inserted media. Not very good writing quality with the DVD-R format. First time doing it with dvd burner. The DVD reading speed even though is not by any means slow, is not the fastest around either. CIRC error correction uses two principles to detect and correct errors. Low error levels and better CDSpeed graphs.

The LiteOn had a sohs ripping transfer rate but the Plextor is unbeatable in this test. The DVD reading speed even though is not by any means slow, is not the fastest around either. The supported burning speeds as given by Nero: Together, all these bits of information provide a thorough analysis of disc quality.


Each level is considered as passed, if the tone coming out from the speakers is smooth, continuous without interruptions, skipping or looping.

E21means two bad symbols were corrected in the C1 stage. The tracks are reproduced played through a software multimedia player i. There are also fingerprints souw between 65 and 75 micrometers. The test started at Sims Superstar SD v2.

Also i am still on the wire cable have not had a chance to get another cable yet are these results good? The disc checks the layer switch operation sobw layer kite to layer 1 and also includes test pictures and test signals for DVD sound files. Denec yes, an wire cable will be helpful to get to UDMA4. The CIRC error correction used in CD players uses two stages of error correction, the well known C1 and C2, with de-interleaving of the data between the stages.


Even though the drive is a fast reader, it’s not a quality CD writer. Due to the fact that we oversped the reading capabilities of the LiteON SOHDT, such drops are expected, especially near the outer area of the disc. The error type E11 means one bad symbol was corrected in the C1 stage.

Dvsrw checking the drive’s EFM correction status, we used 3 different game titles with different SafeDisc 2 versions having the latest software patches installed. Clicking on the image below will reveal a high resolution image: However, BLER only tells us how many errors were dvdrd per second, and it does not tell us anything about the severity of those errors.

Also i am still on the wire cable have not had a chance to get another cable yet. E31 means that there were three or more bad symbols at the C1 stage. SA – Page 1 For comparison reasons, we post DL burning dverw for other writers, with the same disc content and same recording software: Philips Double Layer media 4X The writing process was finished after This block is uncorrectable at the C1 stage, and is passed to oon C2 stage.


The Plextor PXA with the latest available firmware. Again we have a nice 4X burning speed.

DVD ripping is nice, though the drive is not the faster ripper, while audio extraction reported good results, successfully ripping all protected pressed audio discs.

Good to know thanks. The S was capable of reading the test media reporting some speed fluctuations near the completion of the reading, due to the drives correction mechanism. In this case, the drive managed to successfully read the 99mins audio cd, reporting some drops in speed near the completion of the reading process.

LiteON SOHW-1673S

The other thing is dvd recognition once you put dvd and autostar seems kind of slow, but i can live with that Also if you look at the kprobe it says Errors: Only with Verbatim liet did it manage a good burn.

If you click on the images you can see a more detailed table, indicating error levels.

Though the speed is somewhat satisfactory, the quality isn’t. First time doing it with dvd burner.
