I just recently checked out a product known as the Pogoplug that allows you to put your hard drive (even a thumb drive) on the Internet.

All that is required is plugging the Pogoplug into the wall, and then into your router. You then have four USB ports to plug in hard drives, and you can access the info from these drives anywhere after you set up a secure Pogoplug account.

I was surprised that it worked, and worked well. If you want to check it out for yourself, feel free to read my review here.
