    Is there any way to run similar test but for a Network Attached Storage (NAS) disk?

    CHDSK worked for me in windows 10. I had problems with the disc showing 100% in task manager. the chkdsk command worked when all else failed

    My Dell HD test said bad disk, buy a new one (bad sectors)
    I ran the (admin) DOS command above chkdsk c: /f
    I let it run on restart
    Fixed and no more bad sectors. HD OK
    Thank you

    Thanks for the CHKDSK option. It worked on our Windows 10 machine that was not booting and the Windows 10 repair stuff was not working at all. Even a Reset did not work. After the chkdsk c: /f the C drive was repaired and on reboot Win 10 started up normally! BIG THANKS

    Update to my previous post. It now says 633 hours!

  • Tony February 23, 2016

    Alison is the lucky one. I am running the command on a 1TB disk and it says it will take 223 hours! Surely there is a quicker way to fix a bad disk?

    How long should it take the run the disk check through the “This PC” method (the 1st method described)? After a power outage my desktop is running so slow it’s impossible to do anything on it and I remember the chk dsk command from very early pc days. My desktop is currently telling me that it’s Error Checking the local disk (the one I told it to) and about 11 hours and 30 mins remaining – the time is actually increasing – it started off with mins and then 3 hours and now it’s at 12 hours. Is this actually correct or is this an indication of a disk problem?

    Thank you,

      Hello Alison

      Without more investigation its hard to say however your feeling does match mine. It does seem like there is something wrong with the disk.

      Try running this tool and sent the results to us (admin@windowsinstructed.com) http://hddscan.com/ so we help help you 🙂

    I kept telling me I don’t have enough authorization when I try running from command prompt what should I do?

    • Yuri Pustjens February 7, 2016

      Are you sure you started Command Prompt with Administrative Rights? You receive error code 5 I assume?
