On at least two occasions I have heard a sort of clicking noise (one or two at the most) coming from my pc. I have a 40 GB hd primary and a 160GB ide hd slave. I'm not sure if this is my hard drive failing. I have listened to the "failing hard drive" samples on I think maxtor or sony's site and the first sample sounded similar to the noise I heard, only the noise didn't repeat over and over, it just sounded once or twice really quickly.
Also, my system has been crashing and I don't know if this is because of a program I installed or if it is my hard drive actually starting to fail. Is there a way to check what is causing it to crash? If I post the error report the next time it crashes, would someone be able to decipher what the cause is?
