I put in a second hard drive today, the same exact brand (western digital). I made sure the master primary drives jumper settings were "Master with Slave". Then for the slave drive i made sure the jumper was set to "Slave". The IDE Cable is even marked which connector is MASTER and which is SLAVE. So I put the SLAVE connector into the Slave drive. I boot up and it says Cannot Find Drive Please Enter Floppy. Or something along those lines. It says it cant find ANY drive at all. But as soon as I reconnect everything the old way and take out the Slave drive it works fine. the BIOS doesnt even see ANY drives at all when the slave is in there. Why put jumper pin settings on HDs that dont work????????? Im confused. Thanks for any help!
