[qanda]This thread is about the Lite-On SHM-165P6S. Click here to see full specs[/qanda]Weird. I can burn onto disck but cant erase. Will tell disc inserted is not a RW. Did erase ( in a Dell laptop with W Vista ) and now light-on wont recognize disck. WEIRD thing !
Welcome to CD Freaks
I moved this thread to the Lite-On DVD burner forum, where someone in this section may be able to help. The Lite-On DVD recorder forum is for Lite-On set-top DVD recorders, i.e. the DVD equivalent of a VCR.
One thing worth trying is carrying out a full erase with the Dell laptop’s DVD burner to see if this works. A full erase takes a while depending on the disc (~15mins for 4x DVD+RW or ~9mins for 10x CD-RW)
Which firmware are you using, and are you bitsetting to DVD-ROM book type? I tried latest MSOR firmware but found I got best SL results with the previous MSOP firmware on my SHM-165P6S.
