I have a LG GSA-4166B 16x LightScribe drive which I bought about a year and a half ago. I was using only Verbatim media, and verified all the data I ever burned to ensure I won’t lose anything important. At first, everything worked fine, but then I started to notice the problems with the newer Verbatim DVDs designed for 16x speeds.
Basically, I buy two kinds of media, Verbatim DVD+R media which come in spindle of 10 or 25 units, and Verbatim DVD+R LS media where every disc comes in it’s own jewel box. Both kind of discs are made by Mitsubishi Chemical Corporation, have a Manufacturer id: MCC 004, and are 16x certified.
Now, the problem is, at first I noticed the drive would refuse to burn both discs at speeds higher than 4x, and if I burned them at 4x speed, I would end up with lot of CRC errors during verification process. I successfully updated the drive with the official LG firmware (from 1.01 to 1.02), after which, the normal Verbatim discs (those bought in spindles) would burn at 16x, and the verification would pass without CRC errors. The reading speed would also be very good (reaching somewhere between 15-20 mb/s near the edge of the disc). However, the LightScribe media would still burn at only 4x speed (I couldn’t even select any other speed in Nero), resulting in CRC errors on almost every disc I burn, and reading would be extremely slow (barely going around 4-5 mb/s near the edge of the disc, and would sometimes drop even lower at some places). The old Samsung DVD drive I have on another computer (it’s a little older than my LG drive, and never had it’s firmware updated) recognizes that these discs can be burned at 16x, and performs the verification without any errors. The discs burned on Samsung can be read without errors even when put into my LG drive.
So, I’m wondering where exactly is the problem. Both kind of discs have the same info, and I practically have the whole desk filled with coasters I made when burning DVDs (both LS and “normal” ones) at 4x speeds. I thought it was a drive failure at first, and was thinking of buying a new drive. But since almost all discs burned at 16x work without problems, I reckon it may be the problem with the drive not recognizing the Verbatim LightScribe discs properly, or these discs are of lower quality than normal Verbatim DVD’s, despite of having the same info on them.
