Evening guys, I have Mroogled the condition of hard-drive chirping (maybe clicking, doesn't sound like hard-drive clicking 'click' though) as a symptom of the hard-drive going to die. The condition happens every so often, in particular during Firefox (Flash and Java) and Outlook usage. I have backed up, via time machine, and contacted apple via their express appointment. I have analaysed the SMART condition via SMART Utility and it past, so I'm not sure if the hard-drive is on the go. My hard-drive is a Seagate Momentus 7200.4 (500 gb), what are the chances of my hard-drive getting replaced (currently my work-horse laptop), I have 4-5 months left of Applecare. Thanks for reading.
