    Windows checkdisc


    I need some clarification about windows checkdisk. I have been googling it a bit and it says that it scans and repairs logical file system errors. Does that mean physical errors, or does it mean file errors in the windows installation?

    Check disk can cure disk file system errors and can mark bad sectors nothing can cure bad sectors the disk is physical damaged.

    Does that mean physical errors on the drive, or does it mean file errors in the windows installation?

    P.S I see there are many commands you can use with checkdisk, what's the best one to use if i want to do a complete scan and repair of my system?
    For a complete scan and repair, I would recommend "chkdsk d: /scan /offlinescanandfix /r". Its worked for me for a long time.

    Could you explain in detail what these commands means?

    Check disc checks the Disc filing system, and disc sectors for damage and may try to recover and move files to avoid bad sectors that's all.The moved files are usually damaged.That may affect anything on your hard drive, Windows, Programs, User data like documents, photos etc. Absolutely anything.It will do nothing to repair Windows or indeed anything else.The point of doing this is to ensure your HDD is in a reasonable condition to use and install Windows and other stuff on reliably.

    You can get file problems due to things like power cuts. Otherwise you might have a failing disk if these problems persist. Check the SMART disk data also. I generally use chkdsk /f and sometimes the /spotfix option.

    There are a number of switches that can be run with the chkdsk command:
    chkdsk | Microsoft Docs
    Chkdsk is used most commonly to check the drive file system.
    Using the /f fixes the problem drive files found.
    Using the /r attempts to recover readable information.
    The chkdsk commands can be run to scan the whole disk on a storage drive.
    To fix problems with the operating system you can run: sfc /scannow; dism commands, or perform an in place upgrade repair. If there are deeper problems you may need to perform a reset with save files or reset with remove files or clean install.

    A chkdsk /x /r will scan most of the drive with a Windows operating system.
    If you want to scan more parts of the disk that will require additional chkdsk scans.

    Do you mean windows system files, e.g the ones found in the system folders?

    @zbook seems like sfc and chkdsk does two different things, so that only makes it more confusing.

    There is an operating system and there is a drive file system.
    Each one has methods to test and fix.

    Ubuntu/Linux can be installed on a drive.
    A method is needed to fix each operating system installed on a drive.
