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.

Restore Default Startup Configuration for Microsoft Standard SATA AHCI Driver

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_storahci_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The storahci service is using the storahci.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
