I use Windows 7 Ultimate x64 and I am having problems with my optical drives, which are NEC AD-7173S and NEC AD-5170. When I try to burn disc it gives me the "Power calibration error". They read discs really fine, but cannot burn them.
I tried to update the firmware - nothing
I tried to disable Adaptive Link Power Management via your instructions but it says "The power scheme, subgroup or setting specified does not exist."
I tried well lot of stuff but still nothing?
Can You help?
