WH16NS40 - was working, now says "No Disc"

[ben_uk]

I have literally just flashed my WH16NS40 and began ripping films. I ripped Dunkirk and Lock Up absolutely fine. Then I inserted American Psycho and when the disc was trying to load instead MKV brought up loads of text. Sadly I dont have the exact text but there was dozens of lines of mentioning "security certificate" over and over (and perhaps it said "invalid" too) again and SCSI was mentioned a lot. I now cannot load any discs, even the ones that worked fine before (Dunkirk and Lock Up). I have used it for literally a day and now thinks are looking sketchy.

I have only used VLC Player to play the ripped files.

I just tried to insert a regular blu ray and that wont recognise either.

Below is what I see now in MAKEMKV

Either your laser lens is polluted or what is more likely the BluRay laser is dead. You need a new drive.

Shut down your PC for a min then turn back on and it should work again

After 5-8 hours of use?

If it continues to give you problems return it and get a BU40N

I second what Billy recommends

OK thanks, I unplugged the sata cable and re-inserted and its now working again. So what occurred there then?

Optical drives are tiny computers that run the firmware that drives the laser and motors. Sometimes the drive gets confused and needs to be rebooted. Removing power from the drive is really the only way to get it to do a 'cold boot.'
