| Product | Lite-On LH-20A1L |
| Description | 20x DVD burner with SATA interface and LightScribe |
The specifications of the Lite-On LH-20A1L state that the drive is able to write CD-R discs at 48x and CD-RW at 32x. Let us find out how the drive really performs in speed and quality.
Writing Data CD-R discs:
For our data writing tests, we simply burned a full disc using CD-Speed (create data disc) function and burned the discs at the maximum speed allowed.
Write quality:
We will test CD-R discs from many different CD-R manufacturers. To really measure the write speed, we used the “create data CD” function in Nero CD-Speed. The discs were written at the maximum speed that the drive supports. For the quality test, we used K-Probe 2 which is a tool developed by a Lite-On employee. It runs under Windows and works with drives made by Lite-On. Also note that different drives and different reading speeds may affect the results obtained when scanning the discs. We used a Lite-On SOHR-5238S drive with firmware 4S09 and scanned the discs at 48X speed.
A written CD-R disc will always have some C1 errors; C1 errors are easily corrected by the drive’s error correction capabilities. The next level of errors is C2, while C2 errors could also be corrected by most drive’s error correction capabilities; they are not wanted on a good quality disc. A good disc should not contain any C2 errors, and preferably have an average C1 error amount of below 2.0 for the best discs, or at least below 10.0 averages for good quality discs. After C2 errors, there are only un-correctable errors that will make a disc unusable.

C1 errors are quite high at the start of the disc, but the result is still good.
Summary:
CD-R writing quality and media compatibility is very good to excellent with the Lite-On LH-20A1L and CD-RW writing quality is good.
Now let’s head on to the next page where we will test DVD recordable performance….
Reading performance
I have this DVD Burner and it does not recording on any media with drag-and-drop method on Windows XP.
Maybe some of you can help me with that? Maybe it is my fault and it needs some properly driver to install?
If so please write to me: p b o r k o w s k i (at domain) o2.pl
i am also looking for its free region code
