Sometimes, if your PC behaved weirdly, scanning your hard drive with the Error Checking tool is one solution that can help you identify, and correct, a range of errors including file system issues and much more. Once such command that possibly comes handy during this situation is the well known 'chkdsk tool'.
So what exactly does the Check Disk Utility does? This tool is also known as chkdsk (the command you use to run it) basically scan the entire hard drive to find and fix problems. To be precise, this tool scans the file system and its meta data just to fix the errors if it finds any.
Moreover, it also scans every sector on a disk volume finding bad sector. The so-called Bad Sector comes in two forms -- Soft bad sector, which occurs when data is not written properly and hard bad sector, that occurs due to physical damage caused on the disk.
This process is easy to do and it usually takes a few hours as well.
Step 1: Click Start -> right-click My Computer and select 'Properties'.
Step 2: Select the Tools tab and click 'Check'.
Step 3: Select both the options (if asked) that say -- automatically fix file system error and scan for and attempt recovery of the bad sector.
Step 4: Click on 'Scan' button
Step 5: When prompted, select the option to schedule the disk check, and then restart your computer.
Step 6: If you find no errors, you can just click on close once it's done.
