How to Fix SSD Is Read Only in Windows 10/8/7

Yesterday, I received a private message from social  account. It shows “Recently I bought a Samsung 850EVO 250GB SSD drive to store all my games. It runs great for maybe 2-5 days and then the SSD drive seems to be stuck in a read only mode. I can see it in Windows Explorer and Disk Management, but I cannot download any games on it and the disk itself says that it is ready only in Disk Management! I have tried to change it in the properties, but no luck. Any ides on what else I can do? Please help!”

I immediately responded to him, and when I germinated, I decide to write solution post to share with more windows users.
