Reader: I went to the library yesterday and check out a few books about hard drives and learned that some hard disk are connected to the motherboard via an adapter. I’m confused, though. In other placed, these books referred to the adapter as a controller. Which is which? Or, are they the same thing? Computer Doctor: ALL IDE drives technically have the “controller” integrated into the drive. That is why they are called IDE (Integrated Drive Electronics), the term refers to the fact that the controller is built-in to the drive. The IDE connector on the motherboard would be more properly called a “host interface” or “host adapter”.
