Hi I’ve had this Drobo Pro for about a month and it has (8) 2 TB drives. I have it connected directly to my MBP 17" via FW 800. I always keep the MBP running when I go to sleep.
Yesterday I came into my office and noticed that my MBP had froze up so I had to reboot it. When it booted back up I saw that the Drobo Pro did not mount. Drobo Dashboard recognized it as well as disk utility. I tried to mess with it for a few hours with no luck. All I got when I tried to verify/repair the disk I got the Invalid B-tree node size error. So I got on tech support with Data Robotics and they told me to run Disk Warrior.
I ran DW and it took almost a whole day to finish and then I was able to mount the drobo. But now I noticed that 90% of my data is lost or missing and it scrambled my files.
I am very skeptical about reformatting and starting over with this because 1.) I have spent weeks loading about 10 TB to this thing and 2.) how can I trust this again? I don’t understand why I got the Invalid B-tree node size error because I have never unplugged this unit from my laptop and have never unmounted it improperly. The only incident was that my computer froze.
Also I don’t see why its worth having if this unit is so sensitive that this can happen from a “improper” unmount or computer freeze.
Can anyone shed some light on this? I am about to return this unit and find another means for data back up.
