How can make changes to a hard drive being shared with a Windows machine? So, this may be a unique issue and goes to show my ineptitude with Apple products. But, I have a hard drive that I share with my Windows PC that I use for storing all my pictures, music, and movies. The problem is that on OSX I'm not able to make any changes to the drive. I can't rename, add to it, or delete anything. I checked the Get Info on it, and for security it says I can only Read.

I've Googled all sorts of stuff and everything just keeps telling me to "click the lock". What lock?! Am I completely missing something?
You must install FUSE for os x to be able to make changes on a hard drive formatted in NTFS (Windows) https://osxfuse.github.io
