For the last 6 months or so my iBooks (g4,800mhz,1gig ram)hard drive has been stuttering. It gets hung up on opening applications(when i only have one open at the time), playing songs in itunes, and doing just about anything lately. I re-installed the os(10.3.9) twice and its persistently getting worse. It makes sort of a click-click-dudda sound over and over, sort of like it stuck on searching for what it needs to find. This can last for a few seconds to 20 min sometimes, it goes to the beach ball while doing it. I restarted the other day and it took 30min. to get to the main screen. Repairing permissions is becoming a 20min event also while it makes that sound.I use diskwarrior from time to time and this helps but not so much anymore.So my question is do you think it may be that the HD might be dyeing and this is an early sign of it?Any words of advice or just take it to apple, and yes its still under warranty.
