I want to use my external HD (MyBook) for my Time Machine Backup but when I went to back it up it told me that the MyBook was not formatted for it. I used this HD to transfer pictures and documents from my old PC computer to my Mac and it transferred correctly. I did notice that for some reason when it is plugged into my Mac, there isn't an option to create a folder in the MyBook. I wanted to put all my other docs in separate folder as to only have 2 folders on my HD...the backup one and the docs one but it won't let me do it in my mac...it will let me do it if I reconnect it to my PC.

Your My Book WD hard drive is likely formatted to NTFS. That's why you can not create a folder on it from OS X since by default NTFS is read only. You can however, copy from a NTFS drive to OS X.
In order to use the drive for Time Machine it will have to be erased and reformatted as HFS+ Extended Journaled. Be sure to remove everything you need from the drive first before allowing Time Machine to format for its use.
