This is a Drobo Pro connected directly via USB2 to a new iMac. When the iMac goes to sleep (it doesn’t seem to happen when one is working on the machine), the Drobo disconnects from the iMac and gives the message “Disk not ejected properly…” At that time it is not represented in the Dashboard either.
The wires are not being disturbed, and we’ll be replacing the USB cable later today, to see if that’s the problem, but I think we’ve tried that already once before so I’m not hopeful, especially as it only happens when the iMac is asleep.
Most of the time, just turning off the Drobo, waiting until it spins down, then turning it back on will bring it back on to the desktop.
Power cord is plugged into the battery side of a UPS with a brand new battery.
All the lights are green
There are 2 Volumes, both unmount improperly, apparently at the same time.
There are 8 drives, some 1TB and some 2TB
It’s about 70% full.
Sometimes it requires holding the power button for 5 seconds to turn it off.
Could this be a powerpack issue? (Again it doesn’t do this when one is sitting at the computer, thus far only when it’s asleep.)
Any other ideas?
