I’ve been a long time Drobo user. Had a gen 1, then a gen 2 and now I’m trying to upgrade to a Gen 3.
Other details:
Mac Pro
OS X (10.8.3 or whatever it was)
USB port on rear of computer
I bought a gen 3 and noted that I had a hell of a time getting it to mount the first time to make sure the firmware was up to date. Took about 5 restarts and a bunch of work to get it to finally show up.
Finally did. Then I moved the disk pack from the Gen 2 and it took awhile and everything looked great.
Except now it is unmounting and mounting repeatedly. The Gen 2 sits on the same computer with its own pack of drives and works like a charm. But the 3 goes up and down and up and down.
So I bought a new SSD and installed a fresh copy of El Capitain (been meaning to do this for a while). Same problem. Gen 2 is bullet proof. Gen 3 mounts/unmounts.
I bought a Sonnet USB 3 Card for the PCIe slot to isolate it and get better performance.
Same thing.
Dashboard and firmware are up to date.
So I sent the first Gen 3 back and got a second.
Same thing happens.
FML.
Any ideas?
