leave the drive idle for 2 mins with a UHD disk in it you will have the sleep bug WH16NS60 only has 1 build code and its NS60 your thinking of WH16NS40 and WH14NS40 they need NS50.
the sleep bug only happens with uhd disks left idle for 2+ mins and when you try to read it it makes a horrable seeking sound then you need to open and close tray to fix. its not a problem for riping but for play back if you pause a movie or something.

Thanks for the heads up! I only plan to rip so hopefully the sleep bug wont be an issue. Ill try the LG drive you mentioned (official UHD supported) if the asus doesnt work for me. Its twice as much money so I will try the Asus first;)
