Default Behavior

The Microsoft Standard SATA AHCI Driver service is a kernel device driver. In Windows 8 it will not be started until the user starts it. If Microsoft Standard SATA AHCI Driver fails to load or initialize, the error details should be automatically logged. Then Windows 8 is restarting the PC and attempting to use the Last Known Good configuration. If the Last Known Good configuration isn't working properly, Windows 8 startup ends with a Stop error. If you disable the storahci service, Windows 8 will fail to start.
