Hi all, I have the basic Macbook Pro notebook bought October 2008. Not had any problems since I bought it but this morning the internal hard drive just started to spin increasingly fast to the point that it was louder than an Xbox 360 p). After it reached what I imagine to be a peak the macbook put itself to sleep and then reactivated again. I didn't lose any data but it is slightly unnerving though. The CPUs were in use to about 75-80%. All I had open was safari, calender and mail. I have a Lacie USB drive too, but that was inactive throughout. Does anyone have any ideas? Cheers in advance.
