ScanDisk Runs Even Though Windows Shut Down Correctly

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

If the destination device is an 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.
