ABSTRACT:
The present invention comprises two IDE disk drives for connection to an IDE bus, configured as a master drive and a slave drive. In the present invention, both drives are capable of receiving commands from a host computer connected to the IDE bus. Depending on the type of conunand which is received, the drive which receives the command determines the appropriate response to the command and initiates a sequence which, in cooperation with the other drive, ensures that the command is executed properly. Thus, the host sends commands over the IDE bus thinking that only one drive is present, and the drives handle between themselves how to respond to the command in a way that mimics the response of a single drive.
