Please forgive me. This one is too good to pass up. And my sarcasm needs to be exercised at least once a day.
Batty1, what we have here is another example of Green Technology NOT being the answer to our problems.
OK, that's enough. I've got to get back to yard work, Spring cleaning and reorganizing my home network. Actually Batty1 some of what I've learned after I screwed up my HTPC/NAS/Home Server might shed light on your situation.
In researching whether to go back to a RAID 1 configuration for storage a couple of people made comments along the lines of, "Make sure the hard drive is RAID certified."
Apparently WD has drives designed to be used in RAID configurations, and their other drives are designed with specific usages in mind. When I was buying my drives 3 years ago I was choosing between Black, Blue and Green. At that time most people were still saying "Don't use the Green for a variety of reasons." So I chose Black eventhough it was supposed to be a bit noisier than the Blue.
My point. Maybe the Green drives don't like being spun up all the time which they would be in a server type environment. They probably like to take a rest regularly and probably want the system to do the same.
Your answer probably lies deep in the technospeak of the hardware involved.
But I have a simple answer: Gremlins. I've believed in them most of the 30+ years I've been intimately involved with computers. A couple of days ago I was having some weird problems with my kids' ipods. Next day, poof, everything is back to normal. Gremlins.
Good luck on solving your "Green Technology" problem. But I'm guessing the problem is with the Green part, not the Black Gold, Texas Tea. Y'all come back now you hear.
(OK, I'm going to have to explain that last line to the vast majority of you who have never watched the Beverly Hillbillies. Black Gold is oil. And like it or not, oil is what will make the world run for many years to come. ... Better go now before the moderator moderates me off the board for being political."
