Is the drive detected by the BIOS?
Is the BIOS set to Auto detect the drive?
Check the data cable is in the correct way round. 80 wire cables MUST be fitted with the motherboard end in the motherboard. This end is the end with the longest distance to the centre connector. It must also have the red stripe edge fitted to pin1 of the connectors at both ends. Pin1 on the drive is the end of the socket nearest to the power connector.
Try a different cable.
