I got a PD today @ OM and the serial starts with number 4, but the rest are numbers and letter. Seems to be an NEC, which I have two of already, the NEC 1000 and NEC 1100. Both drives have been great and really realiable, too!
I have yet to open mine fearing it was the dreaded BTC, but now after reading another member getting the same serial# I might open and install Monday to see how it goes.
I may go back and try for the Lite-On later in the week for my secondary PC.
