hi, i have a year and a half ibook g4. yesterday when i turned it on...it made weird noises...grinding...clicking...etc. i knew it was the hard drive. so i tried to backup everything. i turned the ibook on the side and that made the noise go away and made it a little usable so i could backup. done. but now the hard drive still makes the noise no matter what and is superbly slow. SMART status is verified though. but it's totally not usable. so i have osx on an fw drive and i can boot off that for now, but the internal hard drive is still connected and tries to run. so everytime i get into finder or anything that remotely reads the internal, it just slows to a crawl and hangs. is there any way to disable the internal hard drive from being used? i know in windows i could jsut right click on the device in device manager and disable...so is there something like that in osx? thanks!
