What is write protection?

How can I remove the write-protection on my external hard drive?

• I'm using a Windows Vista operating system. I have an external removable hard drive connected to it. But everytime I need to add a folder or file, i received a message which said "Remove the write-protection or use another disk. I don't know how can i remove the write protection on my external hard drive. My external hard drive still has a very large space, but I can't use because everytime I add a folder or file, I received write-protection message. Please help me how to solve this problem. Thanks
