I own a MacBook Pro OS X 10.4.11, and it's an old, heavy model from around 2006-2007. On November 2nd, I had left my laptop on overnight with many active programs minimized, and upon waking it up from sleep mode, my laptop made the craziest loudest spinning sound coming from the hard drive compartment on the right side of the keyboard. It sounds like a combination of a leafblower with a loud fluttering sound, and a bit of scratchiness.
I frantically closed all the programs and shut the computer off, worried that it was crashing, so then I had it unplugged for over 24 hours. When I turned it on again, it worked just fine for a few days after that. I thought that the cause of the problem was having too many programs open at the same time, so now I'll be careful and have only one active program at a time.
Then, the sound came a couple more times; On Nov. 7 when I powered the laptop on, using the battery making me shut if off right away before the start-up screen came up. And then it happened again Nov. 13, about 10 minutes after I plugged it in, without any active programs going on during both these times. I am suspeccting that when my laptop was repaired earlier this year, the removal of the hard drive for data retrieval made it less aligned. That may be why it's making a funny (not haha funny) spinning sound. I worry now that work on any sort of project will be jeapordized when the noise will happen again in the middle of working on it. I almost couldn't turn in something for a collaborative art project because of this problem, but before the 3rd time the noise happened, I did turn it in.
I'm going to have it checked out by an Apple "Genius Bar" specialist next week and see if they know what it is that's going on. Until then my internet connection will not be the best. But I was just wondering if anyone else came across this problem with a similar model of Mac laptops.
EDIT: I ended up taking my laptop to the Apple Store Genius Bar this morning, and they confirmed it WASN'T the hard drive doing this, but it was rather coming from the CD drive/ optical drive. Either the fans cooling the laptop probably went overtime, or the CD drive was trying to read something, they said. But since the loud noise didn't happen when I brought it over there, the specialist couldn't really help me otherwise, except to confirm with a device that the hard drive was perfectly fine. So I can't complain too much, because my data isn't jeopardized, but I still worry of this noise.
