Desktop computer running Windows. Never goes to sleep. After I boot the computer and leave the system idle for a while the Drobo S (connected via eSATA) will disappear and the Drobo Dashboard icon in the tray will show “No Drobo is detected”. This can be fixed by some combination of unplugging the eSATA cable, toggling power on the Drobo S to off then on, and/or a reboot. At that point the Drobo S will be visible again and the drives can be used.
I have tried stopping and restarting the Drobo S service (since that can be done remotely and most of the others cannot) and that doesn’t fix the problem.
I’m on Windows 7 Professional x64. Intel X9650 Quad Core @ 3.0GHz. Dell XPS 420 with 4GB of RAM. Drobo is hooked up via eSATA to a Sil 3132 dual port card with latest firmware from SI’s website.
