I have a Western Digital external USB hard drive. I would like to use this as my Time Machine backup HDD for my new MacBook. After a bit of research I've found that I can't simply share the HDD via my Windows 7 desktop - the HDD must be considered an NAS.
Is there any utility out there that would allow me to trick computers on my home network into thinking that the USB HDD hooked up to my Win 7 machine is a NAS? Essentially, I need to publish a USB HDD to the network as a NAS.
