TomatoUSB

1. I'm having trouble figuring this out. I do not want to use external drives attached to the router, but actually within my computer. Exactly what do I do to make this happen?

2. Also, it is possible to only power the HDD's of my computer and let the rest of the PC go to sleep as it is torrenting and being used for DLNA?

3. Lastly, is it possible to make the router actually 'go to sleep' in a way, like a computer? As in, is there way to have WOL on a router so that it only wakes when the connection is being used?

1 - Yes, but yer bass-ackwards. Install the router into the computer, not the computer into the router.

2 - No

3 - No

Thanks, but can you expand on my first question? Shouldn't the drives be mounted in the router to use transmission and DLNA? How would I mount the router if it has no storage? I still don't understand exactly what I have to do.

On another computer with the external USB drive attached, you need to share the drive on the network, so that other computers can access it.
Then, in the router, you can use the 'cifs' function to mount the shared drive to your router. You'll then be able to save and edit files in the /cifs directory, which is the shared external drive.
