Time I got this drive I put the latest FW on it, Burnt a few disc, I always do the DVDInfo Read Error Scan, they were fine, Now I used all these speedhacking and auto bit setting tricks and this drive will NOT burnt a readable disc at all. I’m using CMC Memorex +R. DVDInfo keeps on giving me error reads either at the 60% or around the 90% marks. I just wanted to see if anyone else was having this problem, I haven’t put the orignal FW back on, but will later tonight. Never had this problem with any disc burnt with my LG 4040b.
