I joined the bloggers meeting in Tokyo hosted by Cloud Engines before starting service in Japan, where CEO Mr. 

Daniel Putterman and 

One of my questions was "Does Pogoplug support the sleeping mode of HDDs?" 

The answer was " Yes, Pogoplug supports " Wake on WAN".

However, my HDD never sleeps when attached to Pogoplug. My HDD is Buffalo HD-CBU, which is quite popular in Japan, and this of cause sleeps when attached to may PC.

If there is any hidden setting, please let me know.

Thanks,
