I want to use a Drobo 2nd Gen for Time Machine on a Mac so I need to partition.
If I partition with Dashboard, the size of the partition is not reflected correctly in the OS. If I set the partition at 2TB, it is reported at 2,2TB by the OS. If I set it at 4TB, the OS sees it at 4,4TB.
If I partition using Disk Utility, the OS sees the correct size, i.e. 3TB is 3TB, but the Drobo and the Dashboard only “see” one partition and completely ignore the other one. The blue lights do not reflect the usage of the first partition at all.
I am running Dasboard 1.6.8 and Firmware 1.3.5. I believed that it might be related to the fact that I don’t have 1.3.6, but I can’t install it. I follow the instructions but it does not update. I have now confirmed that my drives do not have 4k sectors so that can’t be the issue in any event.
I tried shutting down and restarting, I reformatted several times in various ways using Dashboard or Disk Utility, performed resets, etc. I also uninstalled and reinstalled Dashboard to no avail.
I need the OS to correctly see the partition size to use Time Machine. I also need the Drobo to see the real capacity used so that it can work properly.
I have read somewhere that the blue lights will correctly report capacity if I turn off Dashboard completely. I actually would prefer not to have Dashboard running all the time, so I am going to try that next. It is going to take a while to copy enough data for the first blue light to hopefully light up…
I have wasted hours on this and I am getting very frustrated.
I am using 2TB Hitachi HD and I am connected by Firewire.
What can I do to solve this? Is turning Dashboard off going to solve the issue? And why is it that the OS sees 2.2TB if I format a 2TB volume with Dashboard?
