drobo disappearing/timing out/becoming unmounted

After updating our Drobo firmware to 1.3.7, the volume keeps disappearing (becoming unmounted) from the computer at random. The Drobo is attached to a 2.4 GHz Intel Core 2 Duo Mac Mini with 8GB or RAM running OS X 10.6.7

I tried unchecking the “put the hard disk(s) to sleep when possible” in System Settings in case something changed in the firmware where it suddenly started using that setting. We’ve never had a problem with this before updating to the latest version of the firmware.

Is it possible to roll back the firmware to 1.3.6 without killing all the data on the drive? Any suggestions about how to get this to stop would be greatly appreciated.

Just curious, but after upgrading to 1.3.7, did you completely shut down and unplug the Drobo?

Thanks NeilR. I found that yesterday after I posted this.
