As my sig shows, I have a 444S@811S. I’m exclusively using DataWrite Classic x8 (Greys) with my 2 NEC drives and get good results @ both 4x and 8x burn (although the 4x is better). At Â£5-99 for 25 these are a really good buy - and from my experience are more compatable (on stand alones) that Ritek -Rs.
Downside is that the LiteOn hates these disks - is there any FW out there (for the LiteOn) which will enable me to burn the Greys??
