Hmmm, looks OK. Have you tried to take those disks and connect them to a PC SATA controller, power up to a DOS prompt and listen for the same sound? If they're quiet it indicates the issue is either in the WD firmware or the way the NAS/Linux talks to the disks. I wonder is other Linux users of this model disk complain about this issue? I found this page on the WDC website that may indicate your disk does not have the latest firmware. If a new firmware is available it can sometimes be like pulling teeth to get WDC to send it to you. http://www.wdc.com/en/library/cs/2579-701321.pdf Also, have you checked the jumper options? Not sure I'd touch them without doing research first!!! http://wdc.custhelp.com/cgi-bin/wdc.cfg ... faqid=3335

Yes, I took each drive and using an external SATA dock, tried them one by one with my computer. I reformatted each drive and mounted them on the desktop. In every case, the drives made the sound for a few seconds after mounting, then became quiet as one would expect for a spun-up drive at idle.

The drives are all factory-refreshed from WD and have the latest firmware. I RMAed the entire first set I purchased to eliminate the possibility of a bad drive in the set as the cause.

I also RMAed my first Pioneer Pro to eliminate it as a variable. I have tested this configuration on three different Pioneer Pros with three sets of the same drives and I'm getting the same result. The continuous clicking only happens in the ReadyNAS.

I agree that this may be a ReadyNAS SATA hardware/firmware issue. I haven't seen reports of this behavior from desktop users of this drive and WD confirms that it is not normal.
