WIN 7 CHECK DISK TYPES CMD...

 

To Run Chkdsk from Command Prompt 

 

NOTE: The chkdsk command can be used on a FAT32 or NTFS formatted disk.

 

1. Open a elevated command prompt or a command prompt at startup.

 

2. In the command prompt, type in the following command below followed by one or more switches that you would like to use below with a space between each switch and press Enter.

 

NOTE: For example, the most common command to run chkdsk on your C: drive is: 

 

chkdsk C: /F or chkdsk C: /F /R

 

chkdsk [drive letter]: [switches with space inbetween]

 

 

Switches that you can use in the command:

 

/F - Fixes errors on the disk. The disk must be locked. If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer. For example, on the C: drive.

 

/V - Displays the name of each file in every directory as the disk is checked.

 

/R - Locates bad sectors and recovers readable information. The disk must be locked. /r 

 

includes the functionality of /f, with the additional analysis of physical disk errors.

 

/L:[size in KB] - Can only be used with a NTFS disk. Changes the chkdsk log file size to the number size in KB you type. If you omit the size parameter, typing /L by itself will display the current chkdsk log file size. For example, to have the default 65536 KB log file for the

 

 C: drive, you would type: chkdsk C: /F /L:65536

 

/X - Forces the volume to dismount first, if necessary. All open handles to the drive are invalidated. /x also includes the functionality of /f.

 

/I - Can only be used with a NTFS disk. Performs a less vigorous check of index entries, which reduces the amount of time required to run chkdsk.

 

/C - Can only be used with a NTFS disk. Does not check cycles within the folder structure, which reduces the amount of time required to run chkdsk.

 

/B - Can only be used with a NTFS disk. Clears the list of bad clusters on the volume and 

 

rescans all allocated and free clusters for errors. /b includes the functionality of /r. Use

 

 this parameter after imaging a volume to a new hard disk drive.
