This afternoon we posted a firmware update for the 2nd Generation 4-bay Drobo that enables support for greater than 2TB hard disk drives. To download this firmware, please go to: http://www.drobo.com/support/updates.php
Please also read the release notes for this new version (1.4.0).
This firmware update now completes the rollout of >2TB drive support for all currently shipping Drobos. Support for the 4-bay Drobo took longer than we thought, but we wanted to make sure that it was implemented and tested properly. This will now allow future drive sizes to be automatically supported.
Thank you for your ongoing participation on this forum.
Can I apply this update using Dashboard 1.8.4? I’m on Snow Leopard, and despite having used 2.0.3 for ages with my V1 this page: http://www.drobo.com/support/updates.php now says I can’t use 2.0.3 with a V1. When I add my V2 to the setup what software should I use?
I have installed a 3TB WD Caviar Green SATA3 drive. The first two times I put it in, the Drobo did not acknowledge the drive. I had to jumper it to SATA2 for it to work, and the Drobo is now into data protection mode. It is a little disappointing to put in an extra TB and have it almost all (931.5GB) go to “reserved for expansion.” Getting an increase in space is going to require a second 3TB drive.
That’s how it works at all capacities. Your biggest drive is always redundancy, and if it’s bigger than the next biggest drive then that part is “reserved for expansion”. Your two biggest drives need to be the same size to get the space increase.
Nice! It’s been a long wait. So what’s the best way to upgrade? I have a unit that has 4x2TB drive. Can I just simply eject one of the 2TB and put in a brand new 3TB? Can I do this live while the unit is running? Or is that not advisable? Should I power everything off, then replace the 2TB with a 3TB, then power on everything? What’s the best way to upgrade capacity? Sorry for the newbie questions. I bought the unit fully populated with 4x2TB, so this is my first time upgrading to a bigger capacity drive. If this works, I’ll buy 3 more 3TB so I can have 4x3TB drobo unit.
I took mine out while it is running. Try not to pay attention to the claim of how long data protection will take (mine says 242 hours!); from past experience, it will be less than that, though it will be a couple of days.
I have the latest version of Drobo Dashboard, but whenever I use it to check for updates for my 1.3.7 [1.254.30359] Drobo Gen 2, it says “Drobo has the latest versions of Drobo Dashboard and Drobo Firmware”
What am I doing wrong?
EDIT: Figured it out, I just hold control while selecting “check for updates”
