My 5N ran out of available useable space. My dashboard informed me to replace the smallest drive in my array which was a 1.5TB drive, which I have already done on a few occasions.
On those occasions when I needed to increase capacity I replaced my smaller drives with WD RED NAS Drives in either 3TB or 4TB models without any issues.
However this time around I seem to have an issue. The new drive has been recognised within Dashboard as an SSD, I didn’t think to much of it at the time as I could still use and access my data and Dashboard was reporting the rebuild was underway.
Unfortunately after leaving my Drobo overnight to rebuild I can no longer access my data on my Mac. My Drobo is available under ‘Locations’ in Finder but I get a ‘Connection Failed’ message every time I try to connect.
My Drobo is also being temperamental within Dashboard and not staying connected for long and causing Dashboard to become unresponsive and it needs to be Force Quit.
The Drobo itself is still flashing Yellow/Green and within Dashboard it’s indicating that Data Protection is in Progress but not giving a time to completion.
After reading other threads it appears that WD RED’s are now no longer recommended by Drobo due to WD using SMR technology in the drives, and it appears I’m not the only Drobo user to be stung by this issue.
My question is how can I fix my Drobo and access my Data? Would I be able to remove the new 3TB WD RED and reinstall my 1.5TB drive to fix the drive pool?
