Hard Drive Checkups

Every time you shut down the computer, Windows tidies up, ensuring all files are saved properly on the drive. When all is well, Windows turns off the machine (or, on older computers, displays a message on your screen telling you it’s OK to shut off your computer manually). The time that elapses between your Turn Off Computer command and the actual power-down moment is the “tidying up” period.

But sometimes, thanks to a system crash, power outage, or toddler playing with your surge suppressor, your computer gets turned off without warning—and without the usual shutdown checks. In the days before Windows XP, restarting the PC after such a dirty shutdown would automatically run a program called ScanDisk, a utility designed to detect and, when possible, repair drive damage that may have occurred as a result of an improper shutdown.

ScanDisk doesn’t exist in Windows XP, but its functions have been reincarnated. You get to it by right-clicking the icon of the hard drive you want to check (in the My Computer window). From the shortcut menu, choose Properties; click the Tools tab, and click the Check Now button (Figure 15-6, top).

Top: Click Check Now in the Properties dialog box for your hard drive. Middle: Click Start to begin a scan of the file structure, folders, files, and other elements on your drive. Bottom: You may be asked to restart the computer, so that the Son of ScanDisk can work during the startup process. If you click Yes, nothing seems to happen at all. Windows is just holding its breath until you actually restart the computer, so that it can perform its scan at that time—a lengthy procedure that keeps you posted as to its status via onscreen messages, and then restarts the computer when it’s over.
