For this reason I keep this trouble ticket open." The Drobo should also be monitoring this sector on its own to ensure its structure is always intact by keeping a copy of the MBR data on different drives in Drobo/in EEPROM/and on the customers system within the Drobo Dashboard App. It does no harm to the system even if the customer does this with no real purpose. Because the Master Boot Record is so vital to the BeyondRAID filing system, a tool should be added to the Drobo Dashboard which allows the user in such a case as mine to rebuild this sector in the event of catastrophic data failure. All I did was try to replace one bad drive, and dual disk redundancy was enabled as well, so it should have had no problem. I then began the vigorous task of ensuring the data on the drive was still working, and I did find a few files that were corrupt, but nothing too major.Īlthough I was able to rebuild most of the data on the Drobo, the issue that corrupted the Master Boot Record in the first place is still at large. I rebuilt the structure of the drive just to be safe, and I found it did have many errors on it, which were then corrected. I ran Disk Warrior and it finally recognized the drive.

#Diskwarrior rebuild full#
TestDisk is an application that runs within a Terminal window, so it is not quite user-friendly however, I was able to re-establish a full mount of the Drobo Disk.At least to a point where I could run Disk Warrior and rebuild the drive, which I completed successfully. The tool is called TestDisk 6.13 ( ), which is an open source program for all variants of Operating Systems. I did, however, find another tool that was able to see the drive and its current file structure.
"Although I did try some of the tools that were recommended, non of them were able to recognize the Drobo properly.
This is the solution to my problem which I had with Drobo, I currently have a trouble ticket open with them and your situation looks similar.
