I just switched from FireWire to USB (because after exiting the screensaver, the drobo doesn’t open again.)… but it’s now worst.
When I rebooted the computer, the POST hang on USB, saying something like:
Detecting USB device…
Device #00x: USB Mass Storage …
And it hang there for hours.
I must unplug the USB cable, boot the computer, then replug the drobo USB cable.
