I have a 2nd-generation Drobo in the house. Once per week, we have a planned power outage (yes, really, follow along) for about 10 hours. House server and media libraries all get shut down cleanly and powered off before power is cut to the house. Not a big deal, right?

Power it all back up 10 hours later and Drobo occasionally says, “Hey, you’re missing a disk… replace the one with the red light.”

Occasionally.

So, I reseat the drive… then wait three days for the array to rebuild.

Three. Days.

Yep, first world problems.

It’ll only get worse as I upgrade those disks to 3 or 4TB capacities.
