Does anyone knows where is the problem?
I turned off the write-cache buffer flushing and then few days later i saw this error in Storage Executive. So, i turned it on again, but it doesn’t work. Of course i did restart after turning on/off this option in device manager.
EDIT
Done. I had to untick two options in device manager (write caching), then restart and then i enabled write caching on the device. Works perfectly.
