Gosh Darn! i Baught a 1TB WD drive last weekend and it wouldnt work so i had to settle for 750GB. Now ur saying 1TB works.. Just great.. If i exchange it now i will loose the 16 Movies i've already recorded.. Darn. O well.. serves me right for rushing out and buying an EHD since i've only had the thing for about a week lol. patients is a virtue.
