I wonder if anyone can help. I recently installed a new 5TB drive replacing a 1.5TB drive, all was fine. Ordered a new 5TB drive and replaced a 1.5TB drive, all fine until I copied new data at which point the first 5TB drive “failed” so I removed it and put one of the 1.5TB drives back all, all fine again.
I tested the 5TB drive I took out and I cannot see any issues with it so after a couple of weeks I put it back in NOT the same slot it came out of, again replacing a smaller drive. Mirroring finishes, I copy data to drobo and the OTHER 5TB drive “fails”
Its currently in the process of rebuilding after I put a 1.5 back in. But this seems really odd to me.
Has anyone else seen behavior like this? can it be worked around? both are Seagate drives, I am running drobo firmware 3.5.12 [8.96.86249]
