Drobo 4bay

Help! I have a Drobo 4 bay and have alternate green and red flashing lights on the right hand panel lights! What does this indicate? Your help please. Thank you!

hi stevenbrooks,
can i check if the green and red flashing lights are possibly green and amber/orange/yellow (rather than red?)

if so, it could just be that your drobo is recovering from a hard drive error (and is rebuilding things for you).
Rebuilds can usually take about 1 day per 1TB of data that you have, but if you can remember how much data you had on it, and approximately when it started flashing, we can try and work out when a rebuild might complete for you
