Hi all,

I don't know which is more effective to HDD. I think /r /f is true but i haven't done it ,however, always checked /f /r ( as my teacher who claims it's right).

But as my thought, after we repair a machine, we have to fix screws. So /r /f is right. Please explain, microsoft OS writers.

    ... but it's better if we checkd three commands in our Internet Cafe or networked computers daily. What's your option?

    We seem to be experiencing a bit of a language barrier, so I will try to explain again.

    If you use CHKDSK /R that means that you are automatically using CHKDSK /R /F. The /R mean that everything that /F does is done as well as anything extra that /R does. Since everything that it does has already been accounted for, there is no reason to use the /F at all.

    In summary, my option is to use CHKDSK /R only. Do not use either of the other ones.

    In addition, it is probably excessive to run CHKDSK every single day. Once a month or when told to do so by the operating system should be more than enough. I believe it has been years since I've used it myself.

    Hi,

    Order does not matter in the switches.

    /F              Fixes errors on the disk.

    /R              Locates bad sectors and recovers readable information

                      (implies /F).

    To see the Command Format open an Elevated Prompt

    chkdsk /?

    How to Fix Chkdsk will Not Run at Startup in Vista (Windows 7 is the same)

    =========================================================

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

      volume          Specifies the drive letter (followed by a colon),

                      mount point, or volume name.

      filename        FAT/FAT32 only: Specifies the files to check for fragmentation.

      /F              Fixes errors on the disk.

      /V              On FAT/FAT32: Displays the full path and name of every file

                      on the disk.

                      On NTFS: Displays cleanup messages if any.

      /R              Locates bad sectors and recovers readable information

                      (implies /F).

      /L:size         NTFS only:  Changes the log file size to the specified number

                      of kilobytes.  If size is not specified, displays current

                      size.

      /X              Forces the volume to dismount first if necessary.

                      All opened handles to the volume would then be invalid

                      (implies /F).

      /I              NTFS only: Performs a less vigorous check of index entries.

      /C              NTFS only: Skips checking of cycles within the folder

                      structure.

      /B              NTFS only: Re-evaluates bad clusters on the volume

                      (implies /R)

    The /I or /C switch reduces the amount of time required to run Chkdsk by

    skipping certain checks of the volume.

    Hope this helps.

    I believe that the correct answer is:

    CHKDSK /R

    Since the /R option "Locates bad sectors and recovers readable information (implies /F)." (from CHKDSK /?) having the /F option together with the /R option is redundant at best regardless of its position.

    Yes, sir.

    I changed my boot logo. I changed my logon screen design. It worked. And I changed my Window 7 the whole theme. It worked probably. But after I checked my HDD by chkdks /f /r, when my computer is restarted, the original Window 7 style was loaded. Where did my changes go? Sir, help me with this problem.
