3 Disks failed, 2 back, still trying case # 20574298
Well, after some happy Knoppix dd_rescue Jedi affairs, the NAS1100 got 3 HDD working, and Netgear rescalate the case; I'm under the impression that more Linux commands are requested in the Tech Suppo...

Just a quick update, I just PUTTY the NAS for be sure that a L3 engineer should not encounter any problem connecting from the Internet to the NAS. All ready to have that elusive connection...
For my curiosity, I place a sfdisk on the unit, I got:

No partitions found
Where you can see /hdc and /hde are the HDD recovered from the dark side of the force, the /hdg is the survivor original HDD and the /hdi is the brand new HDD not partitioned drive.
I understand that partitions over /hdc /hde /hdg are identical, that is for some reason giving me hope to recover data, but, no matter that I put the NAS to boot without check filesystem (as instructed by tech support) the RESYNC option is just not available over Frontview.
I wonder, Is it mandatory to have a partitioned HDD to get a RESYNC available over Frontview? I don't think so, but, I like to ask, as I feel we are close to got an answer, positive or negative.
Let's see what happens, I realy would love to know how to RESYNC over commands, but that seems to be out of my range, as a more experienced Jedi master is requested.
Cheers!
