What is the primary function of the "SCANDISK" command in DOS?

• A. To format a disk drive
• B. To check disk integrity and repair file system errors
• C. To copy files from one location to another
• D. To display active processes

Answer: (B)

The primary function of the "SCANDISK" command in DOS is to check disk integrity and repair file system errors. This utility is designed to scan the file system on a disk for problems such as file fragmentation, file allocation issues, and any potential corruption caused by improper shutdowns or hardware malfunctions. When executed, SCANDISK identifies these issues and attempts to fix them, ensuring that the data on the disk can be accessed correctly and that the file system remains stable. This function is crucial for maintaining the health of a computer system, as a compromised file system can lead to data loss and further operational difficulties. The command not only enhances the performance of the disk by keeping it organized but also helps prevent future errors that could arise due to underlying file system problems.
