Note If you turn off the "Enable write caching on the disk" feature, your disk performance may decrease. Because of this, you may want to monitor system performance after you complete the following procedure:
1. In Windows Explorer, right-click your hard-disk, and then click Properties.
2. Click the Hardware tab.
3. Click the hard disk, and then click Properties.
4. Click the Policies tab.
5. Click to clear the Enable write caching on the disk check box, and then click OK two times.
6. Repeat steps 3 through 5 for each hard disk that is installed in your computer.
7. If the issue is resolved, do not continue with the steps in the "Advanced users section." If the issue is not resolved, continue with the steps in the "Advanced users section."
