Microsoft’s hard disk scanning and repair utility, CHKDSK (“check disk”), was introduced over 30 years ago but still has a useful place today.
Users running even the latest Microsoft operating system can still use the command to examine their hard drives for errors and repair them if necessary.
Here’s how to run CHKDSK in Windows 10
NOTE: Some users who followed the suggested steps were alarmed to find that their hard drive space was significantly reduced after running the command. This result is due to a failing hard drive, as one of the crucial functions that CHKDSK performs is to identify and block bad sectors on the drive. A few bad sectors on an old drive will typically go unnoticed to the user, but if the drive is failing or has serious problems, you could have huge numbers of bad sectors that, when mapped and blocked by CHKDSK, appear to “steal” significant portions of your hard drive’s capacity.
