    Windows 7.1 & 8.1


    Hi Brink -
    My Diskcheck for Windows 7 has always been as follows, will this work in Windows 8 and 8.1 ??

    Run a Disk Check on your main Hard Drive in Windows 7:
    • Click Start and open Computer
    • Right-click on C: (or your hard drive letter) and select Properties
    • Click on the Tools tab
    • Under Error-checking click the Check Now... button
    • Mark the 2 boxes next to Automatically fix file system errors and Scan for and attempt recovery of bad sectors
    • Click on the Start button
    • When the message box pops up, click the Schedule disk check button and Restart your computer
    • Once your computer restarts it will check the drive, don't press any keys so that it is allowed to do so
    This will take (on average) 1 to 2 hours depending on your system, so please let it finish.
    DO NOT force a reboot once started a you will lose data and may damage the computer
    NOTE - If this is a Laptop please plug it into a reliable power source, as batteries may fail.
    The computer will reboot to normal mode once it has completed all 5 stages -

    Thanks for any changes and help.

    Hi Brink -
    Sorry to "double up" on posts, but is a sfc /scannow ever required on Windows 8 / 8.1, as I used this for Windows 7.

    Run System File Check from an Elevated Command Prompt
    1 Open Elevated Command Prompt as per directions
    2 Type sfc /scannow and press Enter (note the space between c and / it must be there)
    3 This should not take longer than 20 minutes to finish
    4 NOTE : Do not touch the keyboard while this is running.
    NOTE - If this is a Laptop please plug it into a reliable power source, as batteries may fail.

    Sorry if these are all fully answered by you already, but other sites give variations on these commands.

    Thank You -

    Hello Knojon, and welcome to Eight Forums.

    Actually, Windows 8 can usually run chkdsk on C: while still running Windows now. If errors are found, then a restart may be needed to repair them though. This would be Option One.

    You can still use the computer as normal when running a SFC scan, but just don't shut down, sign out, or restart until SFC has finished.

    SFC /SCANNOW Command - Run in Windows 8

    Hope this helps,
    Shawn

    Hi Brink -
    The scannow seems the same (in your Version 2) but the system can still be used.

    I just need to adapt my chkdsk version for forum use.
    It seems that chkdsk /f is the version that runs while the system operates and /r is added only if there are problems.
    Sorry if these are not exactly the same as yours, but for some forum work a quick option is used.

    Thanks for the links and advice

    I'm going to give the command prompt chkdsk a try on my old Acer later today because I've hit an unexpected issue while beta testing Acronis 2015. When making a disk image it halts partway through with a "bad sector found " message and options to ignore or retry. The standard dumbed down W8.1 chkdsk option just says no problems exist... and I was wondering how to do a full dskchk check.

    It will be interesting to see if it fixes the issue... or whether its a bug with Acronis

    Well, it seems chkdsk run from a command prompt might have resolved the issue because Acronis now runs without the "bad sector" warning... so I'm pleased. And I guess at 8 yr old and with not just thousands but perhaps 20 to 30 thousand hours of up time that its entitled to an odd glitch.
