After switching master/slave roles, the drives still will not work together… what else can can be done?
At this point, it is recommended that the user separate the hard drives and connect them individually to the different interface ports of the system. If the system does NOT have a Secondary IDE interface, it is recommended that the user install an Ultra ATA PCI Adapter card. By doing this, each drive would then be able to individually communicate with the system. Ultra ATA PCI cards benefit your system by adding support for large capacity drives and enhanced support for data transfer rates by Ultra ATA devices.
