What is Check Disk and what does it do?
Check Disk, also known as chkdsk, is a utility included in Windows operating systems that scans and repairs file system errors and bad sectors on a hard drive. It ensures the integrity of the file system by checking for issues that can lead to data loss or system crashes. By running Check Disk, users can determine if there are any underlying problems with their disk and take corrective actions to prevent further issues.
When invoked, Check Disk performs a series of tasks such as checking the file system structure, scanning for bad sectors, and ensuring that all files and directories are correctly indexed. If it finds any errors, it can attempt to fix them automatically, making it a critical tool for maintaining a healthy computer system and prolonging the life of your hard drive.
Why is Check Disk not working?
There are several reasons why Check Disk may fail to run or complete successfully.
