This afternoon my Nephew ejected one of the drives in my Pegasus R4 system. When I plugged it back in, it came up with a red light instead of blue. The array has been running for a year or more and all of the bays were very dusty.
So...I powered down the array and removed each of the drives in turn, cleaning the dust off each one and placing it aside...ensuring that the order of the drives is correct. I then plugged each drive back into it's slot. When I powered up the array, the first 3 drives turned red (and show as "Dead" in the Promise utility. Is there any way to recover the data on the array???
