Explain about Scan Disk? How scan disk fixes errors?
Answer:
Scandisk is Windows' general-purpose hard drive diagnostic utility. It will find and fix any data errors present on the drive. A "standard" scan checks for any data errors on the drive. A "thorough" scan checks for any data errors on the drive and tests the hard drive for any physical errors. Defrag is Windows' utility for organizing the data structure on the hard drive. Through normal use, the data present on the hard drive becomes scattered across the data area.
