Sadly, the data here may be lost for good but at least CHKDSK makes sure that these bad sectors aren’t used again, so data hopefully won’t go missing there again in the future. As part of its disk checks, CHKDSK scans for ‘bad sectors’-those ruined sections of your hard drive that are either inaccessible or unwritable. If it’s not, the CHKDSK utility attempts to separate the damaged files and save the remnants. CHKDSK simply helps ensure that the information currently on your disk is in a safe, working state. Now you know what check disk (basically) is, it’s equally important to understand what it is not : It’s not a data recovery tool so it can’t recover or repair lost or damaged files.

It also cleans out your computer which can free up disk space-and this, in turn, can even speed up your PC! So, think of it as a housekeeper for a sparkling clean and more organized and efficient home. So, it’s a great idea to get into a routine and use it regularly! In addition to repairing minor hard drive errors, it helps keep your system data organized. CHKDSK isn’t just a convenient tool, but an essential part of good computer hygiene. After CHKDSK finishes a scan, the utility displays a summary of what was found, as well as a status of any actions it performed.

Built into your Windows software, it’s designed to do a disk check (hard drive) for any disk errors in the files and the file system. As the name suggests, CHKDSK is just that: It scans and repairs your drive.
