Take a look at post #214 in this thread:
I had the problem on an older samsung drive and this corrected the problem. It may be the same as you have already done.
Thank you for the quick reply
I already use this solution, moreover it is the only one that works
however, it does not completely solve the problem. I notice that when I turn off the computer, the discs click as if they have just turned on
so I think this is not a reliable solution, moreover, the existence of this solution by the registry proves that it is easy to correct the driver to take care of this bug
does anyone tested this solution on the 15XX version of the driver? I am on the 14XXX version
