Our DroboElite was at about 95% capacity (16TB total (8 x 2TB), only using 12TB with the rest as redundancy) when one of the drives started blinking red (6th slot from the left, Slot #5 for Drobo). We ordered another 2TB drive and it arrived 1 week later.
We tried hot-swapping the bad drive for the new one (didn’t turn off the Drobo, just pulled one out and put the other in) and then all of the lights on the Drobo were a solid red. We were also presented with the following message:
“Too many hard drives have been removed. Please re-insert the removed hard drives.”
So we then tried the following and have continued to receive the same error message as above:
Removed the new drive, put the old one back in. Flashing red light on the old drive and solid red light on the other drives.
Tried swapping Slot 6’s drive with Slot 5’s and vice versa
Tried the Slot Flush method where I turned off the Drobo, removed all of the drives, turned it back on and waited. Then I turned the Drobo off, inserted one drive, turned it back on, let it load, and repeated this step for all 8 drives.
Nothing appears to be working at this point. Thankfully we were backing up to an online solution so anything immediate we can grab. However, anything at least a year or so back was on the Drobo and we can’t access it.
Is all of our data at this point un-recoverable? Should we just reset/format it?
