So my new iMac's HDD is getting temperamental and 2 or 3 times now my I will get beachballed as my HDD begins clicking (a double click every 5 seconds consistently). A restart usually fixes this, but I know that this HDD will die a premature death. The only thing is that it doesn't always happen. Do you think I'll need to prove this to a Genius or they'll take my word for it? I've run diagnostics on the drive and it comes back OK! But I've heard this click noise before and don't trust Disk Utilities prognosis. I've backed up important stuff and am prepared for the drive to kick the bucket, even though I don't expect that to happen necessarily tomorrow but better to be prepared. I only ask you guys, cause dragging a 24" iMac downtown is not my favorite thing to do.
