What Is "CHKDSK"?

"CHKDSK", the short name of "Check Disk", also called ""error-checking tool", is a Windows built-in disk diagnosing and repairing tool. It can help manage the computer files and file system in order and also report the physical state of the assigned computer storage devices, like hard disks or memory cards. For example, when you do not ensure whether your disk or memory card is damaged seriously, you can run this error-checking program on this storage device to see whether it is still healthy or workable.

How to Run "CHKDSK" to Fix Drive Errors?

Generally, there are two methods to run this CHKDSK utility to test your wanted computer disk.

1). Open the Error-Checking Tool from the "Tools" tab of "Properties".

If you do want to check the C partition, here are the detailed steps that you may need:

Step1. Open "My Computer" on the desktop.
Step2. Right click "Local Disk (C:)" to choose "Properties".
step3. Click the "Tools" tab in the open Properties interface.
Step4. Press the button labeled as "Check Now"
Step5. Choose your desired option to start according to your needs when you are given two "check disk" options.
Please Note: NO matter what happens, always patiently wait when this tool is scanning your disk.

2). Run the CHKDSK program by using command lines.

In order to fix some common problems of your C partition with CHKDSK, you also can run it like this:

Step1. Click "Start" to open the "Run" tool.
Step2. Enter "cmd" in the blank and then, directly type in "chkdsk c:/f ". Of course, if you do want to check other partitions, simply change the partition drive letter, like changing the "c" into d, e, f and the likes.
Step3. Type in "Yes" and click "Enter".
Step4. Reboot this computer to run this error-checking tool.

Please Note:

The above mentioned prompt code "chkdsk c:/f" only means to fix the possible disk errors. If you do want to find disk bad sectors and recover disk data, you'd better change that "f" into "r", like entering "chkdsk c:/r". To know more information of this disk, you are also supposed to correspondingly change the prompt code just like:
"chkdsk c:/v"---- Shows the full path and name of every file on that disk.
"chkdsk c:/i"---- Perform a minimum check of index entries
"chkdsk c:/l"----Set the log file size
"hkdsk c:/c"---- Skip checking of cycles within the folder structure

If you do need to extract or rescue the left device data out at first, simply use data recovery software to take chances. Of course, when you do get other device errors, also double check device data well and also update device backups well.
