I have an iMac running 9.2.2 which recently crashed. When I tried restarting from the OS disk the computer wasn't seeing the hard drive. A friend suggested I try Norton Utilities, but it can't seem to find it either. What am I missing? My school system supposedly has a tech person to come out and fix these things, but after waiting four months, I'm beginning to realize I gotta do it myself - unfortunately, I'm stuck and my kids are suffering for it...Thanks a million.
