Just bought a WD external hard drive that was on sale for $99 at Staples. When I got to the counter the sales geek tried very hard to talk me out of it stating the drive was defective, didn't work, his boss tried one, is an expert on computers and had to return it, yada yada... I got the last one on the shelf. It looked like a great deal for a 320G drive. I get home and everything on it says a 320 but when I hooked it up it gave me 485G! It was preformatted for FAT32 so I reformatted it for NTFS and still got the same capacity. It's been working great here all day! Using it to capture video files and sneaker net them to my assistant in another room for editing.
