Drobo FS remote recovery

[TerraNova]

I have 5 disks drobo FS, 2 drives have bad sectors and i have managed to clone them. Urgently needed someone who are familiar with Drobo to recover the data remotely via teamviewer. Please let me know the cost via PM

thanks.

Hi

You need to contact Dr-kiev, member of this Forum

[TerraNova]

I have contacted him, it seems he is too busy.

Can anyone else? PM me please

Hello,

Do you still need an assistance with the unit?

According to your description, we should be able to help with remote data recovery for this Drobo FS.

As a new member, I don't have access to PMs yet, so please feel free to contact me via email (check the website in my profile, address is published there).

Hi Dmitri, check your email. Thanks

Please follow up and let us know how it goes.

I had a DROBO recovery not that long ago, however i got lucky and imaged the 2 failed drives. A limited look at the way drobo goes about creating a raid, resulted in a few gray nose hairs =)

So, you recovered by putting the clones back into the unit or did you manually reconstruct the RAID virtually?

Imaged 2 drives the IT guy said system flagged as failed , sent them back to him , got a check and no further communique. So i guess he just pumped them back in and got to the data.

It is because data written to Drobo is not written directly to the RAID, instead Drobo implements a virtualization platform which has its own proprietary method of splitting data to chunks and distributing them via its own distribution algorithm. I know of nobody who can reconstruct these outside of the native enclosure, though it would be pretty handy to know if it can be done

Why not start with an empty file system and then write a large file consisting of 0 in sector 0, 1 in sector 1, 2 in sector 2, and so on? Then see what Drobo does with each sector.

This is one of the first things I tried back when I first started seeing them for recovery. I created RAID5, wrote a pattern to it consisting of sequential numbering to first byte of each sector, then first 2 bytes, then first 3 etc. Several thousand sectors were written with a Winhex script. Removed disks to check outside of the unit, two of the disks looked mirrored each with a copy of the pattern written to the unit, other two disks were not written to. Data isnt written same as it is in a standard array.

Thanks. I think I'll wait until I get a Drobo job before I start on the patent, though. :-)

We have developed a tool for Drobo recoveries : https://www.youtube.com/watch?v=aA7dix_ ... e=youtu.be

Sorry broken link

Nice Is the tool for sale or just in house?

At the moment we perform the recoveries at our lab, working on a remote recovery model and perhaps in the future we will release the tool to the market

[ReclaiMe]

Ah, FYI we have Drobo reader and some rebuild capability in our ReclaiMe Pro (which is for-sale software, not a remote recovery model).

With Reclaime now selling their tool, I think it's time for you guys to release yours to the open market. I doubt many labs will be willing to pay your rates now if they can buy a $900 program to do it.
