SYMPTOMS
Although Windows may seem to shut down correctly, ScanDisk may run the next time you start the computer.

CAUSE
During the shutdown process, the contents of the virtual cache are written to the destination device. If the destination device isan Integrated Drive Electronics (IDE) hard disk, data may be written to the hard disk's onboard cache but not to the disk itself. When this occurs, the data is lost from the cache when the computer turns off.

RESOLUTION
To resolve this issue, you can download the Window IDE Hard Drive Cache package from the Microsoft Windows Update Web site at:
