EX4100 - USB attached HDD won`t sleep

Hello everyone,

i have made the observation, that physical harddrives (HDDs) that are attached to my WD EX4100 NAS System won`t go to sleep mode even though the right setting is made in the energy saving options.

The sleep mode for the internal HDDs just works fine, just the USB drives keep spinning at maximum RPM and won`t stop even when the NAS is not used for hours.

Is there a way, to enable the sleep mode also for the USB attached drives?

Thank you.
