external hd

how do i build external hard drive? seriously is it hard work is there any soldering required?

It's cheaper and better to build your own - you know you're not getting crap-ass Maxtor or cheap unbranded drive foisted on you (get a Seagate, Samsung or Western Digital). Buy an external enclosure, buy a drive to go with it, put the latter inside the former, then prep and format it within your OS. It's incredibly easy, no soldering, just two connectors to plug in that are impossible to get wrong - if you can use a screwdriver you should have no problems (some enclosures don't even need screwdrivers, snapping together with rails, pins or thumbscrews to hold the drive and case). Just make sure you check what type of connection there is inside the enclosure (IDE or SATA) and buy an appropriate hard drive to match.
