I have a Mac Pro 1,1 (2006) that I bought in 2007.
In the past few months, I've had two of my hard drives fail, and now my newest drive is making unusual noises.


One was an external drive that I used in college (bought around 2003), so not much surprise there, but one of them was only maybe 3 years old (and is internal).  Niether drive is currently connected to the computer.


Now, my current hard drive, which is only maybe 2 years old and contains all my user accounts and data is making weird noises.
It makes a sound like it's activating and spinning up out of nowhere sometimes, does that for maybe a minute and then spins back down (loudly), multiple times a day.

It didn't used to do this.


The other day I booted up my computer and the drive didn't register.

I tried again and it worked fine.


Is there some obvious reason why my hard drives have been failing in the last few months?
I get the impression I should probably back up all my data to another disk, but I just did that twice and it would be a waste of time if I did that only to have it happen again...

Mac Pro, Mac OS X (10.6.8), 3 internal hard drives, 9 GB RAM
