Thanks for real data to work from.
Thanks for the assistance!
There's no signs of surface failure with high reallocated sectors or anything, but your drive is parking it's heads nearly 100 times an hour. Someone else suggested this was a "green firmware" drive, so it might be spinning down and so forth trying to save power, and the OS is complaining because it takes a while to spin back up and become online.
Thanks for reading the tea-leaves for me and pointing that out. I'm sure that that is the problem, as this would explain all the symptoms, as I am guessing that quite a large I/O queue can be generated if it is insisting on going into park that often.
I've heard rumors that there exists an WDIDLE utility which might be able to tweak the firmware which might help.
I will look into it, and see if there is a path out of the woods here. I'll report back once something else is known. Thanks all, for the help.
