Noisy hard drive
I'm getting increasingly annoyed by my hard drive (Seagate ST9500420AS). I'm sure you all know what a hard drive sounds like, but sometimes mine clicks away really loudly.
There is no difference in performance - just noise. It's like the normal clicky seeking sounds have been amplified 10x! Usually I can just put the computer into sleep and wake it back up again to fix it.
Does anyone know what could be causing it?
