I recently bought the ReadyNAS Ultra 4 and loaded it up with 4x1TB Western Digital WD10EARX Green. I run the disks in X-raid2 (Raid 5 on 4 disks) and the performance is great.
Now, the “problem” I have encountered is the same as many others have with the Western Digital Green-series. The drives make a clicking sound when they are idle which apparently is caused by the power saving feature Intellipark. (See link)
Now, there is a solution, which is to either disable Intellipark or extend the time period before it is activated. Default value is at an aggressive 8 seconds (!).
My question now though is how I apply this fix to the disks without tearing down the raid array? Have anyone managed to solve this with the disks still in the ReadyNAS?
Thank you kindly!
