I have an '04 HP 52x cd writer. It has firmware QPS2. I can burn discs on this, or on 2 nec’s (2500a/7900) or an lg, with KHypermedia (CMC Magnetics) and when I scan them on any burner/reader with nero there are some c1 errors, but no c2 errors and high scores.
Whatever I read or write on the hp it has c2 errors and, unless I slow the read speed down to 16x-32x, it produces very poor results. I can write most any brand of discs at 8x up to 48x and the results on the hp are just not good.
My question is if anyone would no if QPS2 is in fact one of the older Lite-on firmware versions, and if flashing this drive to a lite-on with a newer firmware would improve the situation at all. I have read good things about the 52737 itself. I am not having similar good results.
