Hey all... I've been having reoccuring problems with internal hard drives in my 17" Powerbook. I'd like to share my tragic tales with you to get any feedback as to the cause before I go out and buy a new one. The first HDD I had in it was the stock HDD that came with it (60gb, 5400 RPM). About a year and 3 months later, it started making an awful "uhrrrrrrrr" noise. At that point, the HDD was junk because I couldn't access anything and it wouldn't shut up. The cause? My theory is that while driving a month or 2 earlier, I had to stop short and the backpack it was in fell off the driver seat onto the floor below. Not a big fall, but it hit pretty hard in any case. So then, I got the thing replaced from my dad's friend. He installed a new drive (60gb 5400 RPM) and everything was good. Flash forward a few months later (February 14th, 2005), I get the same problem. Same noise, same crap. This time, a friend and I installed the new drive ourselves, and this time I spent a little extra and upgraded to a 60gb 7200 RPM. 10 days later, the drive craps out. This time, though, it's a different noise. The sound it makes is an errant, horrible clicking noise. It almost sounds as if the drive is trying to break itself apart from the inside. Along with this, it makes sharp "tick" noises, much louder versions of the usual sound it makes while reading data. My question to you all is, what the hell is going on? Am I just a bad luck magnet, constantly getting crap-ass hard drives? My dad's friend thinks it could be some shady software or data on my drive that is leaving dead sectors, thus causing the hard drive to tweak out while attempting to read the dead sectors. Is it possible my Powerbook isn't compatible with 7200 RPM drives? I didn't notice as drastic a speed increase as all my friends said I would notice, so I think that could be a possibility. Could a fan be busted? The kid who helped me install it said its possible that there could be a damaged fan or something, but I don't feel it getting very hot. Or is it just that there is something else wrong with the Powerbook? Some logic board or motherboard error that I'm not aware of? Please help, this is causing me immense amounts of distress, as I am very close to just emptying my bank account and springing for a new one. Thanks!!
