Circuit City’s currently selling their Western Digital My Book World Edition 500GB external hard disk drive for $111.96 at on site stores. This deal might be a one-day thing but could also be a “as long as supplies last” kinda stuff as well. The best thing about this deal is that it’s cheaper than even buying a used 500GB external drive on eBay. BTW, don’t buy used hard drives! Not worth the trouble if you must know.
As for usage, do understand that you do not connect the drive directly to your computer with a USB port. You have to hook it to your router using a standard CAT5 (ethernet) cable and access it from your computer that way. I’ve only had good experiences with WD’s products unlike the crap that Maxtor churns out so go out there and get it while the deal’s hot!
