Error DiskPart Failed to Clear Disk Attributes

Sometimes, your hard drive, USB flash drive or SD card may be intentionally or mistakenly set to be read-only (write-protected), which will prevent you from making any changes on the device, for example, modifying the old files on it or writing new data to it.

To remove the read-only attribute, many people may like to use the DiskPart command line: attributes disk clear readonly. However, the results vary for different users. some people remove the read-only attribute successfully while some people fail and get the following error message: DiskPart failed to clear disk attributes.

DiskPart failed to clear disk attributes

Then, how to solve this problem? Don't worry! If you also encounter DiskPart clear readonly not working error, you can read the content below to get solutions.

Fix 1. Turn off the Physical Write Protection Switch

Some external drives (including USB flash drives, SD card, etc.) have a physical write-protection switch on them. If this switch is turned on, it will disable all the writable options on the storage device and therefore DiskPart won’t be able to change the disk attribute to writable.

Hence, when DiskPart failed to clear disk attributes readonly on external drives, you should check whether there is a physical write-protection switch on them. If there is a switch, you should turn off it. Then, you can run the attributes disk clear readonly command again to see whether the problem is solved.

Fix 2. Check the Drive Space Usage and Files' Attributes

Sometimes, the write protection is caused by not enough space or the read-only attribute of files. I'm not sure whether they will also cause the DiskPart clear readonly not working, but you should ensure that there is enough space and remove the read-only attribute of files before you use the attributes disk clear readonly command.

The method for checking the drive space usage is very simple, so I will not make an unnecessary move to show you how to do that in this post. But please note that if you find there is not enough space on the drive, you should follow this post to increase the space: Do You Want to Increase Disk Partition Easily? Here's How.

As for how to remove files' read-only attribute, please follow the steps below:

  • Right-click the file or folder in File Explorer and select Properties.
  • Uncheck the Read-only
Tip: For folders, marking Read-only with a tick means that all files in that folder are unwritable; marking Read-only with a square (default option) means that some files in that folder are writable and some are not. Canceling Read-only means that all files in that folder are writable.

uncheck Read-only attribute

After checking the drive space usage and removing files' read-only attribute, you can run the DiskPart command again to see whether the problem is solved.
