Greetings potential new friends!!! I'm a complete and total Apple/ Mac Noob. I have been messing with PC's since the days of the IBM PC jr., remember those? I stumbled across what I thought was a smoking deal on an iBook G3 500 mhz, 320mb RAM, 10gb hdd, for $14.00!!! So I get it, acquire an Apple Hardware Test CD and figured I go to town. I turn it on and automatically I get this clank, clank, clank...from the hard drive. So I turn it off, put the Test CD in and hold down the "C" Key and it took a while but it loaded and I opted for the extended test. Everything passed but the Airport(doesn't have one) & Mass Storage says not installed. I then reset the pram and I get the apple logo with the spinny thing and then 10 minutes later it goes to this flashing "?" with a folder under it. So I reboot and hold the left alt/option key which brings up the hard drive but not the CD? I've been looking up guides on hard drive replacement from ifixit.com, any suggestions though?
