Each IDE channel can have only one master drive. If there are two drives on a cable, one drive must be a slave drive.
To install an IDE drive, do the following:
Set the master/slave jumper on the drive
Install the drive in the drive bay
Connect the power-supply cable
Connect the ribbon cable to the drive and to the motherboard or IDE expansion board
There's a colored stripe down one edge of the ribbon cable
that correctly orients the cable. If there's no marking for pin 1,
you'll usually orient the red stripe toward the drive's power connector.
Configure the drive in BIOS Setup if it isn't automatically detected.
Partition and format the drive
Each IDE channel can have only one master drive
If there are two drives on a single cable, one of them must be
the slave drive. This setting is accomplished via a jumper on the drive.
Some drives have a separate setting for:
Single - a master with no slave
a master with a slave
If the operating system doesn't see the drive, start troubleshooting by determining whether the drive is receiving power. If the tray will eject, you can assume there is power to it. Next, check BIOS Setup (for IDE drives) to make sure the drive has been detected. If not, check the master/slave jumper on the drive, and make sure the IDE adapter is set to Auto, CD-ROM, or ATAPI in BIOS Setup. Once inside the case, make sure that the ribbon cable is properly aligned with pin 1 and that both the drive and motherboard ends are securely connected.
