How to use Check Disk (chkdsk) commands

Hi,

Thank you for posting in Microsoft Communities.

I have understood that you run check disk frequently and would like to know as to which command to use to repair is any corruptions were found. I will provide you the necessary information.

Check Disk performs an analysis of the disk and then repairs any errors it finds, provided that the disk isn’t in use. The complete syntax for Check Disk is as follows:

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

The options and switches for Check Disk are used as follows:

1. **CHKDSK /F:**Fixes errors on the disk
2. CHKDSK /V: Displays the full path and name of every file on the disk (FAT16 and FAT32); displays cleanup messages if any (NTFS)
3. CHKDSK /R : Locates bad sectors and recovers readable information (implies /F)
4. CHKDSK /XForces the volume to dismount first if necessary (implies /F)
5. CHKDSK /IPerforms a minimum check of index entries (NTFS only)
6. CHKDSK /CSkips checking of cycles within the folder structure (NTFS only)
7. CHKDSK **/L:**size Sets the log file size (NTFS only)
8. CHKDSK /BRe-evaluates bad clusters on the volume (NTFS only; implies /R)

I suggest you to run the CHKDSK /R or CHKDSK /F or CHKDSK /R /F that will repair and fix the bad sector found after the scan.

Regarding Windows 10:

Windows 10 Technical Preview users will be now be getting a new Build 9860. Earlier, it was Build 9841. We made improvements and fixes to the product between 9841 and 9860.  

I hope the above information was helpful. Please reply for any further help in Windows.
