for some time i've hoped that LTR-52246K would come out, but it appears it wont.. so I'm asking now, is there any away way to upgrade my 48x drive to 52x one?
Also, it only lets my burn my 52x Fuji's @ 16x - any way to fix that?
To answer the first part of your question. No proably not. Although you're only talking about an extra 4x so it's not like an oc would really benifit you much in a real world situation.
For the second part. I just assume that the media is not of high quality. I had some Princo CD-R's rated for 40x that would only burn at 16x in my LiteOn 40125S before. Every other media I tried would burn fine at 40x.
