Check the DMA setting in Windows Device Manager. Access My Computer, Properties, Hardware, Device Manager, IDE ATA/ATAPI Controllers, select the controller where your drive is attached to, Advanced Configurations and check if DMA if available is selected in Transfer Mode. If not, select it.
Then access Liteonit site and download the last firmware available (MS0M) and execute it to flash your burner.
My 165P6S doesn't noticeably spin when the computer first power on.
