8 Drive raid 5 volume formatt 21 TB

Post by nickfranco » Wed May 25, 2016 12:33 pm

I have made a school boy error and have formatted my HFS Volume with another HSF - will this software allow me to get my file structure back? folders etc - I haven't written anything to the raid since I formatted it.

The raid has been built through a SAS hardware raid controller there are 8 3TB drives in the raid and I have numbered them in the 1-8 from the bottom to top. there is nothing wrong with the drives as far as I'm aware.

I did send them to a raid recovery specialist but found that they wouldn't deliver on their promise, so I lost faith - they tell me that they have not touched the drives nd that they only made disk images of them.

ideally, I would like to find someone who specialises in this kind of recovery saving me a steep learning curve and potential mistakes.
during my research, this software does seem to be the most comprehensive package.

is there any hope of getting the directory back as RAW recovery would be pretty useless a there is at least 7 TB of data that I need back

Thank you in advance for your help.

unfortunately HFS won't allow to recover the directories and files names nor the directories tree

when HFS formats an existing HFS the catalog si wiped off

The unique recovery is RAW by files types

From which nation are you typing from?

Hi Corsari

Thanks for that it's really disappointing to hear that. I'm in the UK - it's relatively simple to get raw data back but is it possible to get the file names? or it it just a lost cause?
I figured that because the directory has been deleted then there might be a way to of set some values to get the files back.

I've been doing tests on a flash drive and sometimes I get the names and sometimes I don't

is there no way to do this i have potentially a 1-4 million individual files and that will be a nightmare to sort out - will i be able to get date modified at least?

will R studio learn new file types like .c4d and .Prproj ?

As I understand, the physical RAID itself is intact, the damage is done to the volume over the RAID. So, you may work with that volume through the RAID controller.
You may try to recover the files yourself, R-Studio allows you to do so for free. If the attempt is successful, you may buy R-Studio, and recover the files. If not, you'll just waste your time, as the process of disk scanning will be very long.
It's quite difficult to predict the outcome of the attempt. Almost for sure is that you won't be able to recover the whole file/folder tree, only some remnants of it, if the folder structure is complex.
If you send me at least 3 small .c4d and .Prproj files (each of the types), I try to create the description file for them.
