Query: junk

Cavalry CAUE37250 3.5" External Module Hard Drive With 7200RPM 250GB USB 2.0 OutsideNot AS advertized,no instructions,no manual,tech support is pitiful.I am trying to make it work on my own, but I think I will have to junk it.Tech keeps telling me that I should have bought the next(more expensive)higher grade.It would have came with an installation & instruction disc.I think this is called "BAIT & SWITCH"My Advice is STAY AWAY FROM ALL CAVALRY PRODUCTS!!!!!!!!!!!!!!!!!!!!DAVID DRUMM JR.
