OK, I replaced the hard drive because "it could not be repaired" in fsck with a new good sata hard drive and when I go to option it doesn't see the HD! When I have the original HD in and press option it shows the HD with an X on it and the install disk with an X on it, is that normal? Anyways, do I have to write zero's to the hard drive or something for it to be seen on a mac? Why else would it not be seen? any ideas? Thanks in advance
