My Drobo was working fine for at least a year now, but for some reason now when my computer gets back from sleep my Drobo unit is not detected in Drobo Dashboard and only way I can get it back is if if i restart my computer. However, I can still see my drobo drive on my desktop and I can still access my Time Machine. I did reinstall Drobo Dashboard but still the same problem.
Drobo Dashboard 1.6.8
OS X: 10.6.3
