2006 Mac Pro Clicking

[Raynedrum]

I've recently been experiencing a clicking sound coming from my 2006 Mac Pro. I just bought it used about two months ago, and for the first month it was silent, but recently it's been ticking every 5 seconds or so. The ticking each time is accompanied by a whirling sound. On some other forums post I read something about hard drive heads parking, but I do not understand why it continues relentlessly.

It does indeed sound like the click of death the HD makes as it's breathing its last breaths.

Take it from someone who's had almost 20 drives die in many ways in as many years. If it is the HD that's clicking, it's certainly about to fail. You only have days, at most some weeks. Backup if you can and get a replacement.

Yeah, that's a dying hard drive. If it's not backed up, do it now and get a new drive.

I had a hard drive do that, and indeed it's the click of impending death.
