Hi, I really hope that someone can help me with this problem:
Originally, I created a 3 HDD Linux RAID5 compound using a Synology DiskStation. Afterwards, I deleted all the existing partitions using the Windows 7 Disk Management tool in order to make a new setup. A few hours later, one of my servers crashed, but on the RAID5 of the NAS was a very important backup, which I urgently need now.
The good thing is, that (in my understanding of disk formatting) I just deleted the partition table. I did not overwrite anything since I deleted the partitioning in Windows.
So I tried to restore the original formatting using TestDisk via the Parted Magic live CD.
Here are screenshots of what I get, when I perform a quick search:
It looks quite good, in my opinion.
But Testdisk won't allow me to change the partition status of more than two partitions. I tried almost every configuration, but I always get a "Bad Structure" whenever there are more than two partitions, that are not marked as deleted (D).
How can I restore the original formatting?
Thanks a lot!
Regards, Marco

Re: Restore partition table of 3 HDD Linux RAID5
In Options, set align partitions to No. Try again a search, Are you able this time to set the md0 and md1 partitions as P(rimary) ?
Note that you will need to boot from a Linux LiveCD/LiveUSB (ie. Fedora) to access your data if the NAS failed to mount the partitions.
