Hi,

I have a Lacie enclosure that has a setup with 2 500gb disks configured as 1 drive of 1TB, the only partition created for the whole drive is HFS+ journaled, but the controller in the enclosure is gone and so the drive refuses to mount anymore.

I have been able to remove those two disks from the enclosure and connect them using USB ports and a program called R-studio (Raid recovery program) check that the setup the controller in the enclosure was using was both disks concatenated (Not Striped). And so configuring that option in R-studio I could be able to get back all the information.

But before I got a license for r-studio for just one use, I would rather buying a new 1TB disk and try to write all the information of those two disks in this new one. I can use Mac or linux machines to do it, and I think it should be ok use DD command in linux to concatenate those two drives into the new one in the right order to get it working again in the new disk and I will reformat the old ones, but I am not sure.

So, is it possible in this scenario to write both disks into a new one using DD? Any hints how the command would look?

Thanks,
