Check your hard drive for errors in Windows 8

Keeping your hard drive free from errors is essential to the performance of your Windows 8 computer. When it comes to computer repair, this is one of the first things I do. So, if your experiencing problems opening an application or file, it may be time to check your hard drive for errors with Windows 8 built-in disk checking utility, CHKDSK (checkdisk).

There are two ways to run CHKDSK, standard and advanced. Here are the procedures for both.

Standard hard drive error checking in Windows 8

  1. Go to the Start menu.
  2. Right click the Start menu background to bring up the app commands.
  3. Select 'All apps'.
  4. Scroll to the 'File Explorer' tile and left click on it.
  5. Left click on 'Computer'.
  6. Right-click the hard drive that you want to check, and then click 'Properties'.
  7. Click the 'Tools' tab, and then, under 'Error-checking', click 'Check Now'. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  8. Select 'Scan drive'.

Advanced hard drive error checking in Windows 8

  1. Open a Command Prompt with Administrative privileges (click here for instructions)
  2. Use the following command line syntax(s) and parameter(s) to run CHKDSK:

CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B] [/scan] [/spotfix]

volume Specifies the drive letter (followed by a colon), mount point, or volume name.
filename FAT/FAT32 only: Specifies the files to check for fragmentation.
/F Fixes errors on the disk.
/V On FAT/FAT32: Displays the full path and name of every file on the disk. On NTFS: Displays cleanup messages if any.
/R Locates bad sectors and recovers readable information (implies /F, when /scan not specified).
/L:size NTFS only: Changes the log file size to the specified number of kilobytes. If size is not specified, displays current size.
/X Forces the volume to dismount first if necessary. All opened handles to the volume would then be invalid (implies /F).
/I NTFS only: Performs a less vigorous check of index entries.
/C NTFS only: Skips checking of cycles within the folder structure.
/B NTFS only: Re-evaluates bad clusters on the volume (implies /R)
/scan NTFS only: Runs a online scan on the volume
/forceofflinefix NTFS only: (Must be used with "/scan") Bypass all online repair; all defects found are queued for offline repair (i.e. "chkdsk /spotfix").
/perf NTFS only: (Must be used with "/scan") Uses more system resources to complete a scan as fast as possible. This may have a negative performance impact on other tasks running on the system.
/spotfix NTFS only: Runs spot fixing on the volume
/sdcleanup NTFS only: Garbage collect unneeded security descriptor data (implies /F).
/offlinescanandfix Runs an offline scan and fix on the volume.

The /I or /C switch reduces the amount of time required to run CHKDSK by skipping certain checks of the volume.
