RAID Reconstructor vs LaCie 5Big NAS

If you have a problem with deleted files on a LaCie NAS, you ask on the Tech Support Forum:

[someone] have got a Lacie 5big [and need to recover some data from it]… It is a 5 disk raid5 array. [so they put 4 disks into windows PC]…where I hoped to use raid reconstructor and captain nemo to get to the important files

My first problem was that win7 listed the disks in disk manager with each disk having 7 healthy partitions, but wouldn’t show them as active under my computer. Likewise, it would appear that Raid Reconstructor couldn’t see them as well.

I then moved on to r-studio, which could see them…but saying that there was no file hierarchy found…

If there’s a solution to getting the disks to appear to Raid Reconstructor… Otherwise, any other advice on the situation would be appreaciated…

Looks like a set of multiple issues,

  1. Only using 4 disks out of 5 is a nice trick indeed. As it is a RAID5, you only need 4 disks to make it readable.
  2. Captain Nemo is largely irrelevant in this specific case. WinHex may have been handy, but that’s a whole lot different ballgame.
  3. Disk Management cannot make Linux partitions active or mount them in any useful way, do not expect much from it.
  4. RAID Reconstructor only works with entire disks, not partitions. While we are at it, ReclaiMe RAID Recovery has the same limitation. Both of these are not really useful for NASes.
  5. R-Studio will work, but requires precise RAID parameters. Eventually, this comes as a solution after the original poster tries multiple combinations of RAID parameters, and the disk order. The disks in the array are not in the bay order:

    the numbered 1-5 bays on the Lacie 5big actually did not house the drives in their ‘correct’ order. The raid drive 1 was the Lacie drive 5 [and so on]

Well, could we have dealt with this? Home NAS Recovery handles partition tables properly, checked. It will figure RAID parameters, including disk order and whatnot, checked. XFS filesystem, checked. Looks like yes, Home NAS Recovery can do this job.
