Primary channel

Updated: 04/26/2017 by Computer Hope

The primary data channel is the main channel when more than one channel is available. When referring to an IDE/ATA hard drive, the primary channel is what the first master and slave drive connect to the motherboard or interface card. If the connections are color coded, the secondary channel is usually black, and the primary is blue. If the connectors are not color coded they are labeled as "IDE0" and "IDE1," IDE0 (IDE<zero>) is the primary channel.
