I am having problems with my Lite-On SHW-1635S recognizing DVD Dual-Layer data discs. I have not always had these problems. The drive worked fine until a couple of months ago. Now when I insert a DL data disc, the drive does not recognize it on the first attempt. The drive stays closed, and I can hear it making sounds (trying to work). I end up needing to eject the disc, reposition it, and try to insert it again. Eventually the disc finally works, and the drive finds the data on the DL disc, but sometimes I have to eject and reposition the disc 5 or 10 times before it finally works. I am using Sony discs. I have cleaned the lens on my drive. This problem only occurs with DVD-DL discs. DVD+R and CD-r/RW all work fine. I have DMA turned on.
I found the firmware (DR16YS0Z - YS0Z.exe) on Liteon’s website, and it gives this error message:
“No matched drive detected!
This utility is only for Lite-On DVDRW SHW-1635S drive.
3-0-0-0 E:LITE-ON DVDRW SHW-1635S YGS4”
I looked up the firmware at the CodeGuys website, but they do not have YGS4. I downloaded the OmniPatcher, but I am afraid to use it because I don’t really know what I am doing, and I do not want to ruin my drive. Maybe someone can point me to a step by step guide/forum post for what I need to do. I am experiencing information overflow, and I am not sure who’s advice to take. I uninstalled the drivers for the drive, and widows detected it and reinstalled it, but the problem still remains.
My computer is an eMachine W3107 (Gateway), it uses the nForce nVidia chipset stuff. I’m on Windows XP. If you need more information, please ask.
Thanks for any help.
