Windows Vista comes with a large number of disk repair tools that can ensure the safety of system hard drive data. These tools can easily repair disk file damage caused by unexpected events such as sudden power outages, and to some extent, they can also repair bad sectors on the hard drive.
To access these tools, enter "cmd" in the Vista Start menu and press Enter to open the Command Prompt. First, you need to determine which partition requires repair. For this example, we will check and repair the C disk partition. Input "fsutil dirty query c:" (the colon after "c" must not be omitted), and after pressing Enter, you will see the system analyze that volume C is not damaged.
