Just a quick heads up. Someone posted a few days ago that Norcent's new 52/32/52 CD-RW was actually an LTR-52327S. Well their new 4x DVD+R/RW is actually a Lite-On LDW-401S.
I just picked this drive (Norcent DW412) up at BB for $149 with a $20 MIR. I am glad to hear that it is a Lite On, though. I wasn't sure when I bought it. But I knew that I could come here and find out some good information on it.
The Lite-On P/N is printed right on the drive: LDW-401S.
