Thank you so much, dude! That's exactly what I was looking for.
How do I make an image of my Mac HDD so that I can put that image on my PC?
The part where it's about sharing files from a Mac and a PC on a network, I never knew that was possible. I did some poking around and found this guide:

Is that what I'm looking for too/related to sharing files between a Mac and a PC on a network?
Also, the exFAT format.. That can be used on Mac and PC without reformatting? So can I make my USB use that format?
Another question: Can't I use Carbon Copy Cloner to clone my iMac HDD to a folder then share that folder to my Windows PC?
