Please log in for more thread options That's because you have a polarized cable. Most cables for desktop IDE
drives are not polarized (e.g. most cables have all holes open). Your
statement that "Nearly all IDE females have the piece of plastic
blocking in the middle" is incorrect. Many do, but most do not.
