NV+ factory reset

Hi all.
My drives were corrupted by repeated bad powerdowns caused by a bad UPS. Bad situation. As a result I have had some experience with recovery software. EaseUS® Data Recovery Wizard is an excellent piece of software and, in the past, worked very well on Windows (NTFS) formatted drives. It also was able recover a ton of files from my EXT3 formatted ReadyNAS Dou v2 drive. However, they are in RAW state. This means that they are identifiable as a file of a particular type, but they are named in a serial fashion (not the original names). Some image files are striped (not a complete recovery, but close). This is fine if you can bear with renaming everything and cropping a few images. It is surely better than nothing! Also, even though it lists AVCHD files (.mts, .mt2, etc) as a file type in the menu, it did not recover ANY files of this type. These video files occupied the majority of space on my drive. There are other video files (.avi, .mov,. m4v, .mpeg, etc) that it did recover, and there is a chance that it just pulled the AVCHD "wrapper" off of the video files and .m4v files remained. In any case, I was not satisfied with this result.

Since then I tried DiskInternals' free program called, DiskInternals Linux Recovery; http://www.diskinternals.com/linux-recovery/
I did a test with it, letting it run for about three hours. I stopped it and it showed me what it had accomplished. It had mapped out a whole host of files, with file type and names intact, including many AVCHD files (extensions M2TS, MTS and M2T). I have run into one issue which may be mine only... I have let it run over the entire partition twice (around 18 hours for a 1TB drive) and both times it gets hung up at about 85% complete. When I force close the application I lose the scan information. I am hoping that I can get it to go through the disk or, that I can stop it just before it hangs next time.
Hope this helps! Let me know how it goes for you.
Peace-

Nice find--I wonder though if the "hung at 85%" has to do with XRAID (isn't that what the Duo uses?). So I wonder if their Raid Recovery product would work completely, instead.

Update on Diskinternals software... SUCCESS
Maxblack may be right that it has something to do with the XRAID file structure. I tried the Diskinternals Raid recovery software but to no avail.
However, I tried their other freeware program Linux Reader (http://www.diskinternals.com/linux-reader/) and it was able to let me browse all of the contents of the disk immediately, without time or effort; no actual recovery necessary. I think this is interesting. How can it do this if the native host (ReadyNAS) can't read the disk? Linux Reader allows you to access the directory in a "Windows Explorer" type view. You can select the folders or files that you want to recover and add them to a recovery list. When you run the recovery list in lets you choose a directory to copy to, then you just sit patiently while it copies the files over. Bottom line, if your NAS drives become corrupted due to bad shutdowns or something similar, this is the software to use. ALSO, if you are a ReadyNAS user, and you do not backup your NAS to a NTFS usb mounted volume then this is the software to use if you need to recover your files from a crashed NAS to a windows machine. I will keep this one on hand since I run three separate businesses off Dou v2's.
I hope this advice creates a shortcut to success for myriad of Ready NAS users.
Peace-

Good for you. Thanks for the update.

I did yesterday download their "Boot CD" which I haven't looked at yet but includes both Linux Recovery and Linux Reader. Seems almost too good to be true (as a freebie that is).

After à bit of experimenting and trying, my brother inlaw and i manager to retreive almaar all files (3,8 tb)
Blog on how we did it will follow.

That's wonderful Reinier; by all means post what you did to recover your files.

It is too good to be true! I have used their apps on palm and android and gladly payed for them. Consider donating, especially if it works out for you. Open Source rocks! Good luck.

Hey,
thanks for the update about diskinternals set of helpfull tools.

I wonder how you proceed this recovery with the readynas NV+ ? was it over the network ? or did you installed disk1 of the nas into some USB box ?
looking forward to getting some explanation.
cheers

I did the same thing. :slap:

Performed a Factory Reset and thought I had lost everything.

Here's what I did to fix it.

First I did nothing else to the NV+

While it was displaying "Waiting on RAIDar" I turned the unit off from the switch in back.

I then performed the OS/Firmware Re-install procedure. "press reset button ~5 sec."

The NV+ rebooted "took about 5 minutes" and when it was finished everything was back to normal. all shares and everything. Other than the things that are reset normally from the OS/Firmware reinstall. :D

I've been through all the directories on the NV+ and all files are where they should be and work.

I hope this helps. This just happened to me today, and while I was looking for a solution I stumbled upon this forum post.
