The Read Only attribute in Windows 11/10 protects a file from being overwritten, modified, or deleted. As the name implies, when you set the Read Only attribute to a file or folder, you can only view its contents instead of modifying them. Hence, you can use this attribute to add write protection to your file or folder. In addition to the files or folders, you can also set this attribute to the disks and disk partitions. In this article, we will show you how to make Disk or Partition Read-Only in Windows 11/10.

Does Windows 11 have a partition manager?
Windows 11 has a built-in tool to manage disk partitions. This tool is Disk Management. You can use it to create new partitions, merge existing partitions, extend a partition size, etc. In addition to this, you can also use the built-in Command-line utility, Diskpart to manage your hard disk partitions. You can launch the Disk Management tool via Windows 11 Search or the Run command box. However, third-party free Partition Managers are also available.
Why Windows 11 doesn’t recognize partition?
There can be many reasons why Windows 11 is not showing your hard disk partition(s). The problem may be associated with your hard disk driver. Open the Device Manager and expand the Disk drives branch. Any warning sign on your hard disk driver indicates that the driver is not working correctly. In addition to this, it is also possible that the drive letter is not assigned or the hard disk partition is hidden.
