How to fix Windows cannot run disk checking on this volume in Windows 10[ 5 ways]
Since Windows cannot run disk checking on this volume because it is write-protected error occurs as the volume is in read-only status, you can fix the error via removing write protection from the volume. Five effective ways are listed below.
① Remove write protection in CMD
② Set the write protection switch to unlock position
③ Edit Windows Registry Key
④ Clear read-only attribute via Diskpart
⑤ Format the write-protected partition
Remove write protection in CMD
When you can’t run” chkdsk n: /f” due to write protection, you can type “chkdsk n: /
f/r/x” (“n” is the drive letter of the partition on which you need to run this
CHDKSK command.) and hit “Enter” to solve this problem. This command can fix errors,
locate bad sectors on the disk and unmount disk.
Note: If your system has been set with write protection on removable
device, this command will be invalid and the error “Windows cannot run disk checking
on this volume…” will still appear.
Set the write protection switch to unlock position
When your drive is with a physical write protection switch you can check whether it is in lock position. If it is, you should adjust it to unlock position. Then, you are able to run disk checking without the error message above. If your drive is without such physical switch or the switch is on “OFF” side, you can overlook this solution.

3. Double click WriteProtect, and set the “Value data” to 0.
4. Close Registry Editor.
Clear readonly attribute via Diskpart
