Hard drive going offline

I have a drive that has been periodically making a clicking sound
(like it's shutting down), but it's temporary--everything seems to be
back online when checked. It does not sound like thermal recal. No
messages in the event queue.

There are nine drives in this system, so it's difficult to tell which
one is doing this. Mostly Seagates from 300 to 750GB, if that matters.

Is there any way to monitor drive activity to track this down?

Likely it is tho, just sounding different to what you expect.

The only real way is to have one drive at a time as the only one on to work out which one is doing that.

Get the SMART attributes (not just the status) from
all disks and look for suspicuous values.

Clicking hard drive = imminent drive failure. Back up and replace the sucker.
