The chkdsk program needs to check all structures on the disk, including ones the Operating System would be using if it was running on that disk. Therefore to check the disk that Windows is installed on chkdsk must run before Windows is started, so that those structures are not in use. If you have multiple disks on the machine the other ones (i.e. that Windows is not installed on) may have chkdsk run on them at anytime. Note: there are some utilities other than chkdsk that can check a disk that is in use by the Operating System. They perform a "Live Disk Check" instead if they find that the disk is in use by the Operating System by skipping checks on the structures where the conflicts occur and checking the rest. Obviously this is not as complete as the checks done by chkdsk, but it can be done anytime.
There are four steps to running the chkdsk utility on a PC. You can learn exactly how to go through these four steps by going online to WikiHow- run chkdsk. They will walk you through the process.

chkdsk /r Locates bad sectors and recovers readable information. chkdsk /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. chkdsk /p Performs an exhaustive check even if the drive is not marked for chkdsk to run. This parameter does not make any changes to the drive.
