humble3d Posted May 15, 2015 #1 Posted May 15, 2015 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. 2
