I have a five bay Drobo FS that recently started showing a yellow light on the top drive slot, which was occupied by a 2TB Seagate mechanism.
But the message it gave me was “Add a drive”, not “Bad drive” or “Drive failure imminent” or “head for the hills” or anything like that.
I have tried:
reseating the drive
using compressed air on the empty drive slot, then re-seating the drive
[*]swapping the mechanism for a new, known-good drive
…to no effect. The drive light remains yellow.
Is this a Drobo hardware problem? Can I expect it to limp along for a few more years or is it a sign that total failure is imminent?
I should add that I removed the Seagate mechanism and was able to reformat and mount it on my desktop PC, without any issues.
