I dont know.. My drobo has 4 1 tb drives in it. But I formated it for 16tb. so, when I upgrade drives, I dont have to reformat. You might want to do the same thing before you fill those drives up. On my mac, it shows as a 16 tb drive, with 13.7 available, but it shows the true capacity only with the drobo desktop.

I just bought a Drobo, and PogoPlug. I also bought 4 2tb drives, and setup my Drobo as raid 5, giving me 5.4tb of space. But when I installed the PogoPlug, and the Mac drive utility, it wiped out my raid 5 and replaced it as a Raid 0 (8tb of space//no redundancy). On top of that when I look at the drive in Mac's drive utility it says it is Raid 1 Mirrored...I used NFS+ as my drive format.
I also, tried disconnecting the PogoPlug, and plugged my Drobo back in directly to my Mac using firewire, and re-mounted it. As a result, it still says 8tb of space Raid 0.
Any ideas or help would be much appreciated.
I set my formatting to 8tb. It will probably be a while before I could get to 16tb. You mentioned another thing that is annoying me. Since I installed the pogo drive, the drobo dashboard isn't working. Does anyone have any idea if there is a way to still use the drobo dashboard while using the pogo drive?
You might still want to rethink that. By formatting to what you have now, and not for future drives mean when you do eventually upgrade, you have to reformat the drobo then, either loose all your data, or find somewhere to park 6 tb of data, reformat, and re populate the drives. I have had to do that once, but I have a second 4tb raid array to move things to. But now, all I have to do is eject the full drive, and install the new, bigger one. (And its getting to be about that time..) as far as your drobo desk top, I can't help you much.. my pogo is 30 miles away from my drobo..
Actually, from what I read in the Drobo docs. All setting the formatting size does, determines how many separate volumes are created. If I expand beyond my formatted size of 8tb, then Drobo will simply create a second volume...that doesn't bother me that much.

Update: Okay, so I checked a little further, and it looks like it didn't wipe out the drobo's drive map. What it does look like it's doing is display the physical hard drive space, and not the logical one. In other words, it is displaying the total drive space (In my case 4 2tb drives = 8tb), and not displaying the total useable space (In my case 5.4tb//Raid 5).
Can someone change this so that it displays the logical space instead?
