I have two Drobo’s - a first generation (USB only) and a second generation (USB/FW), both four-drive units. Both have been connected to a Time Capsule through a USB hub, and have been working fine for quite a while. Recently both drives went offline simultaneously. I connected both to a Mac for direct testing. The current status is:
-1st Gen Drobo: Looks to start up ok (normal light sequence), then goes into sleep mode. Dashboard doesn’t see the drive at all. Neither does System Profiler or Disk Utility.
-2nd Gen Drobo: Does the same as the 1st Gen when using USB, but if I use Firewire it works fine.
I’ve tried multiple USB cables and ports, plus verified the Mac saw other USB devices on those ports and cables fine.
Q1: What the #$*@? Has anyone seen this happen, where multiple Drobo’s lose their USB ports simultaneously? The USB hub is still fine (although I’m bypassing it for this testing). Any thoughts on troubleshooting further?
Q2: If I move the four drives from the Gen1 to the Gen2, will I still have access to the data? I’d like to pull everything off the Gen1 if at all possible.
Q3: Any idea what repair costs might be, if worthwhile?
