I will say, I have a ws14ns40 drive and i was only having about a 75 percent success rate ripping UHD disks with plenty of scsi errors when trying. i updated to the recommended ws16ns60 firmware and after that the drive is faster, quieter, and has no more issues ripping any discs. just FYI. Thanks ...

Thanks for the help; I won't be updating. If the difference is only slower rips and the sleep bug I can certainly put up both rather than risking bricking my drive.

I need a little firmware updating advice. I've read the forum for the past couple of weeks, so I'm slightly less than clueless, but just slightly . I've had a WH16NS40 since 2015 or 2016. Here's the drive info from MakeMKV: Drive Information Manufacturer: HL-DT-ST Product: BD-RE WH16NS40 Revision: 1...

Same thing for me. 10.6.8 on a MacPro (1,1).

Reverted back to 1.9.2 and all is working well.
