Hello

I have a Thunderbolt My Book Duo WD Drive which is connected to a Mac running Mavericks. I have read the emails about the auto reformat issue after upgrading to the new OSX. If you aren't aware, it basically re-formats the drive without you noticing.

When this took place the other day, my Mac reformatted the drives as two 2 separate partitions, which is back to the default, instead of the usual single raid drive (Raid 0).

In total, I have lost 3TB of data, with only 1TB as spare storage space. I was in the process of backing up this drive to the cloud but as you can imagine, it takes a long time to do. I only managed to backup 16%.

I have done a scan of both the new partitions to see if my data is there, and it is. Only issue I can see is that some files are smaller than expected, I'm guessing that's because they are split over the two hard drives.

How can I recover the data so it pieces it altogether correctly? Do I just do a data recovery on each partition or should I raid the drives again and recover that way?

As I have both hard drives, without any mechanical issue, there must be a way to recover the data.

Any help will be appreciated.

Thanks

Matthew

Yes you want to recreate the RAID-0 as it was originally as your data is striped across both drives. To do this you will need to use the correct drive order and stripe size.

Also it is best practice to take images of each drive and perform your data recovery operations on the images.

Thanks for the help! Issue I have is I don't have any spare hard drives to make duplicates.

I think I will have to send the drive off to a professional. I just hope they can get my files back because it is going to hurt me if they can't.

Thanks again.

I'm a professional, if that helps. Where are you located on this planet? If my company isn't within a reasonable distance, I can refer you to labs I would trust.


I'm located in England, the South West.
