I have two hardrives in my mac. One 80GB Master, and another 35GB slave. I have the 80GB set to Device 0 Master, and the 35GB is set to Device 1 Slave. There is another option for slave, its like Device 1 (Slave) Present. Should I have it set there? I ask because when I restart my computer, the machine will give me a gray screen with a system folder, and a question mark in the middle. It cant find a system. So, to boot up, I unplug my 35GB, and restart. Then, right after the white screen with the gray apple in it, i plug it in. It boots ok then But I am sick of doing this. Could someone help?
