I bought a LG WH16NS40 a while back and thanks to these firmware flashing guide here was able to have it read UHD discs (now it shows as a WH16NS60).
I had some issues with the drive yesterday and it kept causing the USB bus to reset it and no matter what computer I hooked it to (it is in a Vantec USB enclosure), it happened every time. It is only 4 months old, so I called LG to have it replaced. The 1st thing they had me do was power it on and hold the eject button for 5-10 seconds (until the tray opened). According to the support rep, this erases all firmware stored information and "resets" the drive firmware back to pristine condition (it does not alter the firmware version, etc).
This instantly fixed my drive - just figured I would share since it is a popular hobbyist drive and a quick fix for some issues I suppose.

Re: LG Optical Drive Firmware "Reset" method
My question is did you at any point power off the vantec case? By unplugging or switch.
Or were you bringing the PCs to the drive?

Of course - multiple times as I moved it from machine to machine.

Re: LG Optical Drive Firmware "Reset" method
So, I have finally determined what causes the drive to stop functioning (completely) when trying to backup discs.
1. It must be a UHD disc the drive is trying to read.
2. The disc must have blemishes (be dirty) or obviously scratched
After the drive tries to copy from it and fails, the drive will no longer read any discs until the reset method from LG is performed. I am unsure if the firmware I loaded that changed the model is the issue, but there was no firmware for the WH16NS40 model, so I cannot verify. Reminder: I bought the NS40 and flashed the NS60 firmware to it.
At least now I know how to operate it properly

Re: LG Optical Drive Firmware "Reset" method
I've never had a LG drive need that kind of reset. When one of my LG based drives flakes out, a full power off then power on is enough to cold boot and reset the drive so it works again.
It is always good to have one more thing to try when troubleshooting, however. Thanks for the tip.
