Without speciifying any parameters it will run and report any errors that it finds. Here are the parameters for chkdsk:

/F - During the disk check CHKDSK will correct all found errors. All
corrections will be written to the disk, so it is reasonable to use the
/C parameter to save the previous condition of the disk.

/C - CHKDSK will save the correction backup information on a disk,
specified after the parameter without space, to a file named:

undo_(checked_disk).chk

You should not save to the disk, which is under checking. This
parameter may only be used together with the /F parameter.

If the CHKDSK command detects "lost" clusters on the disk, you are
prompted with a question: Convert lost clusters to files? If you type
"Yes" , the CHKDSK with /F parameter will write every cluster to a file named:

FILEnnnn.PTS,

where: nnnn - is a hexadecimal number, starting with 0000, FILEnnnn.PTS files are created in the main directory of the specified disk. These files can be then viewed and used, if they contain useful information.

/S - During the disk check CHKDSK will use only the first FAT copy.

/U - With this parameter the CHKDSK will restore the initial condition of
the disk if the corrections were made using the /C switch. A drive
containing the backup information should be specified immediately
after the /U key with no trailing spaces as:
undo_(checked_disk).chk

WARNING! If the disk has been modified after correcting the errors with
the /F /C parameters, e.g. files were amended, deleted etc., then the
/U parameter should not be used to avoid new errors.

/V - CHKDSK, will display all file names and their paths.

unless you add the /f parameter, "chkdsk" will just look for problems but not actually fix them. run "chkdsk /f" to fix any problems also.
