I cannot find the manufacturer's website, that's why I posted here. I've tried CDFREAKS already, they only offer LH-16W1P. When I try to intall it I get an error saying that my drive does not "match" the firmware. I don't know if it makes any difference, but my drive model has the prefix "DH", not "LH", however, that's as close to my model as I can find, so far.
I don't know for sure if I need a firmware update, I'm just trying to work out the possibility that I need one. My drive might be bad so I'm just checking everything before I throw it out.
The drive will not play some DVD movies, even if they are bran new. I have another DVD/CD drive in my PC that use for the DVDs the RW drive won't play. Someone said this might be due to copywrite protection software in the DVDs to make it difficult to copy........I don't know if that's true but I'm just checking around, anyway.
Also, I just burned an RW disk, took it out momentarily, and then reinserted it and the drive wouldn't read the disk. I used the "live file system" in Windows Vista to do this. Then, using CDburnerXP, I burned another RW disk so I have a "mastered" format of the same files and my burner wouldn't read it either, after taking it out and reinserting it.... I can't even use CDburnerXP to blank the disk, when I click on the "erase" option it says that my disk it not "rewritable"....
