Now read this>> I have a pack of 4 drives that are not accessible by the Drobo, and Dashboard reports the drives as raw.
Tech support was contacted, and I was advised that most likely the data is corrupt. A diag file was sent to support, and I was told that there is a possibility that the data is recoverable, but I was on my own or I need to go to a recovery service. I was given the method to place the drive in RO mode, which I did. I was told that certain people had success with certain recovery software, and these were verbally mentioned, but they were the same mentioned on the Drobo site FAQ section, but I was told that Drobo does not endorse any package.
At this point it should be noted that the Drobo was shut down, except to get the Diag file on Drobo Tech Support instructions.
I followed the instructions, and reinserted the pack once in RO mode. This is when I discovered that the Drobo continues to write and update even in RO. Tech claims that should not be the case. I ran several recovey programs. The first program found hidden system files, but no data. Later that same recovery program reported variations on these system files, thus indicating that even in so called RO mode the Drobo continues to do housekeeping. I was not able to write or add data, but able to delete the Zentimo file, which reinstalled upon another boot up.
So… what is happening here? Are we in LaLaLand? Ostrich behavior? Any query on data integrity or restoration is considered ‘rant’. I guess when you loose a more than a terrabyte of photographs, and there is no resolution, except to tell you to restore, maybe it is a rant, particularly when other raids can be recovered.
I did clone the drives, so I can try again, but I’m concerned.
BTW, so called Firewire, because it does not work! Constant loss of connectivity, and that may part of the cause, and later documented by users.
Oddly, I have a LaCie Quadra connected by Firewire, and never had a problem, and still running. Similarly, I had a WD Studio, and it worked fine with Firewire. Rant? or lack of support for an interface which is flawed and not properly implemented in Drobo.
