Go to any electronics store and watch the clerk's expression very carefully when you ask for a hard disk drive. Did you two go to the same school?
Hey dumbass, I was trying to be polite before, but you obviously didn't get it. Your WRONG beeotch! From www.whatis.com, and I quote: "In a personal computer, a hard disk drive (HDD) is the mechanism that controls the positioning, reading, and writing of the hard disk, which furnishes the largest amount of data storage for the PC. Although the hard disk drive (often shortened to "hard drive") and the hard disk are not the same thing, they are packaged as a unit and so either term is sometimes used to refer to the whole unit." How do you like them apples?
in english its a storage device. Ecnal so really you knew, and just wanted to waste forum space by acting all geeky.
