When I RUN chkdsk i get.Warning F parameter not specified. running chkdsk in read only mode what is this ?

whenever i try to chkdsk in safe mode(dos prompt) this message always shows then after a while my pc hangs.

Answer 1

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.

The chkdsk will only check the disk. It won’t make any changes to the drive if it finds errors.

got to Start -> Run -> type cmd

When the command prompt opens, type -> chkdsk /?

This will give you a listing of extra commands and how to use chkdsk and what the F parameter means.

Answer 6

To scan a drive try
SpinRite
http://www.grc.com/spinrite.htm

Also Ultimate boot cd is an awesome tool
Try http://www.ultimatebootcd.com/

chkdsk can be crappy at times.

Try this though before you try the above (assuming you are using NTFS and not FAT)

Run

chkdsk /f /I /C

then
chkdsk /f /I

then
chkdsk /f /C

and finally try
chkdsk /f ->give it a couple of hours to run. It might seem like it is hung up

Answer 7

Suggest you schedule Checkdisk to run, when you restart your computer.
