Hello guys. After I installed a second harddisk into my computer and set the jumpers; put the original one to Master and the new one to Slave, my original Harddisk won't boot anymore. After the "Intel" Screen, I get the message "Non-system disk or disk error, Replace disk then press any key ... Boot Failure". This is a big problem since I didn't have anything backed-up. How could this happen? Could it be Electro-Static Discharge (from my hand touching the harddisk components during handling)? Is there anyway I can retrieve the data on it or make it work again? Please help. -Thank you, JJ.
