After an unfortunate hard-drive upgrade which completely messed up my Drobo (http://www.drobospace.com/forums/showthread.php?tid=2460), my Drobo finally managed to enter the ‘protected state’ again after two full weeks of intense disk activity, multiple reboots,etc. However the file system is now marked as unformatted and the Drobo doesn’t mount.
Here’s a quick overview of the current state:
- 1st gen Drobo with 4 drives
- Initially formatted under HFS (OS X)
- All drive lights are now green
- Capacity gauge is about 80% on the blue diodes
- Drobo shows up in Disk Utility but with no partition mounted
What would now be the best to attempt to repair the file system and attempt to recover my data?
I have at my disposal:
-OS X Disk Utility
I have also heard that R-Studio might be good at recovering RAID partitions. I don’t have that one but if that is the way to go I’m ready to purchase it.
I tried running a simple Repair Disk in Disk Utility and it stops after a few seconds with the following message:
Verify and Repair volume “disk5s2”
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Invalid record count
The volume Drobo400 could not be verified completely.
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Disk Utility stopped repairing “disk5s2”
