I want to purchase a external hard drive with network connection but have a option to get an external hard drive with usb only connection for a good price. can i hook this up with a usb print server and hook that up to my router(router does not have a usb connection) so i can have access to the hard drive from all computers hooked up to the network? any other suggestions? i think a usb print server is about $50 and an external usb drive starts at $100+ and file servers start at $300+. any suggestions on what option works best for me. i do not want to carry around an external HD between computers and want to share this storage space. thanks!
