Win10 run chkdsk command Daquan

chkdsk is a Windows system comes with a disk repair tool, usually after the computer is turned off abnormally, the system will automatically call the chkdsk tool for disk scanning and repair. At the same time, we can also open a command prompt on the Windows system and manually run the chkdsk tool for detection and repair. In the latest Win10 system, Microsoft has not abandoned this classic tool, but also used several new command parameters in the Windows 8 era to meet more abundant needs and achieve more powerful functions. The following MS chiefs will share with you the parameters and functions of the chkdsk command:

chkdsk command + parameter format:

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