router question (hooking usb hdd drive up)

[DonRSD]

ok. im about to get another wireless router.

anyway.....what i want to do is hook up my 1tb external hdd to the router.

i have 3 laptops in the house, so hooking up the external hdd to a laptop doesnt really work as the laptops are portable.

is there a way to hook up the usb connected 1tb hdd to an Ethernet port on the router so i never have to move/unplug the hdd?

i know some routers offer a usb port for this reason......but im asking if i can buy a Ethernet to usb adapter and use the 1tb hdd in that regards by hooking it up into an Ethernet port?
