I just googled my problem and got somebody who has nearly the same problem:
We were on LaCie products and I am now trying to copy the data from one RAID to the new DROBO S RAID. For the third time…
I am not able to mount the DROBO S after disconnecting from one Mac to another. Drobo Dashboard sees the Drobo (5x WD Green 2TB) but I cannot mount it.
Any ideas?
If I am working directly on the drobo (on Mac A) its working seamlessly…
When you moved from one mac to another, did you shut down the Drobo S first?
–> I used the “eject” command from OSX
Maybe it’s also a drive-failure…but how can i check that with quickly with 5 drives? If I am trying to format the drobo, the first try isn’t successful. After the second, third round I have the Drobo volume on my desktop…
You should not be using the eject button. You should be going into dashboard and using the “shut down” command button when moving from one computer to another.
If a drive failed, the drive light would be blinking red next to it.
If you were having format issues, swapping cables would more than likely help.
