I guess it's hard to know without the model number, but in todays new Target sale paper, they have a Western Digital Elements 320GB portable hard drive for $59.99. Does anyone know if this is a good quality hard drive? Is this really as good a deal as it seems to me? I don't know much about external hard drives. I would like to have one for backing up my computer (pictures, videos, I-Tunes, ect.) and another to use with my Dish Network 622 receivers.
