Flashing Yellow Lights

My Drobo S indicator lights have been slowly blinking yellow lights for about a week and my iMac will no longer recognise the drive. I looked around a few sites and saw this is meant to show that the Drobo is protecting data and it should not last too long. It has happened before but stopped after a few hours. What does this mean when it won’t stop for an entire week?

hi tipicard,
usually, the protection/rebuilding process, lasts for about 1 day per 1TB of data that you have on it (though it could be a bit slower if something is accessing the drobo too)

can i check how much data you have on your drobo, and also if the lights are actually flashing/blinking yellow and green?

Paul! Thanks for the detailed explanation! It became clear!
