How do I know if my hard drive is failing?
iBook starts intermittently. Apple appears and the wheel spins but will not boot. Sometimes it's just a gray screen. Have run disk utility from the operating system DVD. It fails to repair permissions and disk. When it does start, some of the applications work others just have the spinning color wheel. I have already sent for a replacement hard drive from ifixit, so I am hoping this will solve the problem. Sometimes I can hear some soft clicking coming from the hard drive area.
