Ideas greatly appreciated.

I have 3 hard drives installed, Taken off case, but I cannot seem to tell which one is tick tocking.

Suggestions of how to test which one. Got HD Tune free, but not helping me.

Help.

Thanks.

And if the above fails, physical disconnection.

Disconnect the two that are not the OS drive.
Power up
Is the noise still there?

If not, power off and reconnect one of the others.
Is the noise there? If so, that's the one.
If not, it's the other one.
