Will using a simple USB to ethernet adaptor be sufficient for connecting my external USB hard disk to router for networked storage?
The only sort of usb to ethernet adapter that i am aware of add ethernet to a computer (usb PLUG with a RJ45 [network] SOCKET) and cannot be used for attaching storage to a network! you will need something like this: Linksys Network Storage Link NSLU2 - NAS server [which i found on froogle, price sort low to high, usb to ethernet NAS - Froogle ]
