IDE (Integrated Drive Electronics) is much more that just wires on a connector. It is a complete interface for data transfer including controller and hardware. It is also a Parallel interface. USB (Universal Serial Bus) is a serial interface, also with a controller. The process for both (if you want to refer to it as a process) is data transfer. You have apples and oranges as Parallel and Serial data transfer are quite different.
Can any one tell me that a ide to usb cable can be done by my own without purchasing ? .
