I just replaced my older LG GSA with a used GSA-4163B that I bought off eBay (from a commercial seller who offers a whole bunch of these drives). The sticker on the drive says it’s a 4163. No other buyer of this drive and seller seems to complain about the problem that I have:
My 4163 is recognized as a 4120 both by the BIOS (updated to the latest version) of my Asrock 775Twins-HDTV R2.0 and by Windows XP.
I found this issue mentioned only once on the net and no hint as to how to resolve it.
(As of now, I can’t tell if any actual problem emerges from the drive not being correctly recognized. I’ve been trying to burn some 16x DVD+R’s - all the same brand - but could only burn them at nominally 4x, which, in fact, turned out to be more like 0.8x). Don’t know if this is a problem with the drive or the media.)
I can’t flash the firmware of the drive as the updater says it can’t find a target drive.
Thanks for reading.
