Hey MR. I posted in another thread about my MacBook's HDD clicking and having problems. The problem happened again a few weeks ago and I took a video of it. I had school exams and such so I didn't have a chance to upload it until today, plus I forgot. What reminded me was that my MacBook started clicking again, randomly but not completely freezing. I'm hearing clicks from my HDD every couple of minutes, so as we speak I'm doing a full backup just in case anything happens. Since the last time it froze, I have done the following: Removed my XP partition Started using Firefox Why did I mention XP? - 2 weeks without any clicking whatsoever after purchasing the MacBook - 2 weeks and 1 day I install XP (obv. I'm doing a rough estimate in time) - 1 day after I installed the partition, I was at school and the computer started clicking while I was doing my assignment! It froze, then I got the folder with the question mark. So I pull the battery and it's fine (assignment gets recovered by Microsoft Word Auto Recovery!) Why did I mention Firefox? Well, every time the computer would freeze and start to click, I would be using Safari. After using Firefox since the beta came out, I have noticed that it doesn't freeze as much as Safari does. Plus the 3 finger swipes finally coming to Firefox made me switch. http://www.youtube.com/watch?v=ua1X1zhOU1A *I just uploaded it, so if it doesn't load be patient.
