CHKDSK short for Check Disk checks the state of the hard drive and correct any errors it finds, if possible. It can be useful for troubleshooting read errors and other storage related errors. It has been in Windows for quite a time. There are multiple ways of starting CHKDSK in Windows 10, in this tutorial we will show you the 3 most common ways.
Run CHKDSK trough This PC.
1. Open File Explorer (Former known as Windows Explorer).
2. Click on This PC.
3. Right-click the Hard Disk you wish to run CHKDSK on.
4. Click on Properties

5. Click on Tools in the Properties window.
6. Under Error-Checking, click on Check.

CHKDSK Will now start to run on Windows 10.
Run CHKDSK trough Command Prompt
1. Open an elevated Command Prompt (Press the Windows + X button at the same time, then choose Command Prompt (Admin))
2. Type the following command, and replace the X with the drive letter you wish to scan: “CHKDSK X:”, we suggest you use “CHKDSK X: /F”, only then it can correct errors.
3. Hit the enter key, Command Prompt will now start CHKDSK.

Run CHKDSK from Cortana
1. Simply type the same command as you would type in Command Prompt, so CHKDSK X: /F and replace the X: with the drive letter you wish to scan.
2. Cortana will automatically start Command Prompt and Execute the command.

We hope this tutorial helped you to start CHKDSK in Windows 10. If you need more help on how to run CHKDSK then please feel free to ask.
Tnx for the help.
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
Great!!! Explanation! Thanks!
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!
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?
Hello,
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,
Alison
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?
Are you sure you started Command Prompt with Administrative Rights? You receive error code 5 I assume?
Great!! Thanks explanation
