I have a Mac Pro, 2.8 GHz, quad-core Intel Xeon, 4 core machine. Two weeks ago, my second internal HD disappeared. That morning the computer was making clicking sounds when I booted up - it still does. Also, when the computer comes back up from sleep mode, it clicks. What can I do to fix this?

Sounds (Ha!) like a bad hard drive. Have it replaced.

You can try using something like Diskwarrior to repair the file-system, but it is highly unlikely that will work if the drive is making odd sounds.

Thanks, that's what I was thinking. Could I just remove the bad hard drive? I have the pre-installed HD, another 2TB HD, plus another 2TB external HD I use for backups. I am assuming this is overkill and I don't need to replace it. – Sara Apr 4 '12 at 13:58
You should just be able to remove the bad drive, yes. – EKW Apr 4 '12 at 14:07
