On both i have externals WD Drives, a My Book Essentials 3 To (USB 3.0) for the (1), using a Hub Belkin, and an Elements Desktop 3 To (USB 2.0) for the(2).

The hub may not be recommanded, i understand, but i have tested without, nothing. The drive connected to the hub is the My Book Essential, i may found the solution using the smartware utility, i switched of standy by originally to 30 mn.
I hope it will work. For the Elements desktop there is no smartware …

For this last one, funny thing is, the support send me this in exchange but took 6 month to admit it was not a Elements Desktop, as stocks are low they prefer to sell them instead of …
