As far as I could understand, Sony’s DW-Q30A device is a LiteOn 1635s with Sony on the front panel and identification info.
If it is really so, can I be sure that it can do all sorts of things LiteOn drive can do (especially PI/PO analyzing), and has the same write quality? And will I be able to upload LiteOn’s firmware to it (in case it gets updated faster than one from Sony)?
Yes, I know these are quite newbish questions , thank you.
P.S. And as to PI/PO analyzing - is there any list of LiteOn models which can do that sort of thing, or I can assume any of them (more or less recent ones) can?
