The Check Disk tool searches your entire hard drive for errors and fixes them. It is also known as chkdsk because that is the command you use to start it. In the long run, it can truly assist prevent larger issues and data loss, even though it’s not a very interesting tool and can take some time to run. Chkdsk, depending on how it is executed, can accomplish the following two tasks:
- The primary purpose of Chkdsk is to repair any logical file system problems it discovers while scanning a disk drive for file system integrity and metadata. These problems could be caused by misaligned time stamps or file size information about specific files, corrupt entries in a volume’s master file table (MFT), or flawed security descriptors linked to files.
- Optionally, Chkdsk can search for damaged sectors by scanning each sector on a disk volume. There are two types of bad sectors: soft bad sectors, which can happen when data is written incorrectly, and hard bad sectors, which can happen when the disk is physically damaged. By fixing soft bad sectors and designating hard bad sectors so they won’t be utilized again, Chkdsk makes an effort to resolve these issues.
In the properties window, switch to the “Tools” tab and then click the “Check” button. In Windows 7, the button is named “Check Now.”
