Here's the actual examine of the target machine (I'm using a different one so disk designation is different as the target machine has only V2.6.3 available):

@Phil: do you think there's a chance with my crude way or is there a better one?

Here's the additional Info (from the start):
a) Machine is a defective QNAP TS 859TS Pro 8 Port with a 2.6.x Kernel and an old 2.6.3 mdadm.
b) from a 8 disks md five failed during a few hours due to BadBlocks on five disks (beginning and end of the disk)
c) I transferred the datas via ddrescue and one (HD6 to be precise) via Kroll recovery to 24/7 RAID HDs (Seagate Constellation)
d) I saved the disks after recovery to our SAN for backup reasons (that took most time as our leased line is quite slow for such amounts
e) I recovered the partition table & volume table via testdisk on the disks where the starting area was defective
f) the Disk7 (=dev/sdg) failed after a few weeks; with the SAN Backup it was replaced by an available spare drive (WD) until I get a new one.
And here I am: three disks with no md superblock (I guess the HDs with the BB at the end of the partition).
My two platforms are always the same hardware (QNAP) just with different OS (the onboard DOM) and the newer PartedMagic2014 with Kernel 3.12.
