I have just shut down my drobo running fine on an imac and then connected it to my macbook pro. When it connected it said that 1 drive was faulty. I then plugged in a usb2 drive to the macbook and the drive went green and all was well. I unmounted the usb drive and the bad drive went bad again. I then connected it back to the imac and all was well again.
What on earth is going on?
btw it it connected via firewire
