Windows 7 Sharing to windows 8 and vice versa

Hi there,
I have a desktop running Windows 7 and a laptop running Windows 8, I am also in a homegroup. Now I want to be able to share my hard drive on both computers with each other but not allow anyone else to view it. I would also like to allow read and write access for both computers too.
How can i do this?

right click the drive icon - share with

Question, why would you want to share the whole drive

Click to expand...

Just to save the hassle to share each individual folder. I don't want to give the homegroup access to everything all i want is just both my computers access to each other whether that is a password or something
