RAID recovery - unexpected node type -27 at file header

Postby aparis » Tue Sep 05, 2017 7:43 am

Hello, I'm trying to use RT to recover a 3-drive RAID that shows the following error message: 'unexpected node type -27 at file header' (see attached picture).

RT sees the RAID volume right away and displays its name properly on the left but when I ran a full scan on this volume it only was able to find RAW data (this RAID had an HFS+ partition).

So I went ahead trying to create my own volume set and none of the different combinations of these 3 drives gives me the proper HFS file structure that I'm trying to recover. (Here is a download link if you're interested to see the saved scan of the 4 combinations I tried:

Does anybody have any idea what else I could do to try to recover this RAID volume? I'm really surprised that it shows up immediately with its proper original name to the left but yet I can't seem to recover the HFS volume. Am I missing something here?

Thanks for any help.

What is the type of the RAID and what has happened to it?

Just taking a quick look at that scan results box, I see the first several Gb are all 'unrecognized'. Is it safe to assume that some data was cloned the wrong direction, overwriting the beginning of the volume with blank or encrypted data? Or did you start and then stop an encryption process?
