Lacie ethernetdisk 4tb NAS device need to recover data

I have the above mentioned unit and would like to recover the data I had stored on it.
I tried using erd commmander 2005 which recognizes that the volumes and drives exist but does not recognize the file format.
This drive has the capacity to hold 4 terabytes of data and is a bunch of dynamic drives in a spanned volume.
I would like to know a free program I can use to recover the data.
The device does boot and I was able to run the repair option from the recovery disk for the operating system. The drives are visible in erd commander's disk management viewer.
I would also like recommendations on a nas device that has redundancy built into it.

I would be very wary about buying any of these NAS drives that has a capacity in excess of that available on a standard SATA drive.  A volume that spans more than one physical drive in this way has poor prospect of data recovery, if one drive goes you might lose everything - there is no redundancy even though sometimes the tag RAID 0 is applied to certain configurations of this type.

I think you need to determine how the disks inside the box are joined together, this article gives a few possibilities:-

As an electronic engineer and programmer I propose the following:
Take out all drives.
In another machine back them up if they have a format recognisable, in example ntfs....
In case of a faulty drive try using "GetDataBack" to save whatever possible and store in another drive - same model, capacity...
If there isn't any mechanical fault in the drive the above program will recover 99.9% at least ( I used it)....

If you want my oppinion maybe one of the NAS drives has a fault and the total system can't work...
If you fix the problem, sometimes only a "chkdsk" needed, it will work again...
But the wisest choice is to backup and replace ALL drives with newer and fresh models...

If THIS is your device then since it noted there that it has Windows Embedded the most probable is that it will also uses NTFS so my previous post has a meaning...
In contrast with WD MyBook world that uses LINUX and slows down my network here (But working without a problem 2 years now)....

The data recovery option chosen would need to have knowledge of each of the physical drives to make sense of them.  Analogy: With a book where the Contents and Index had been stripped off and destroyed, the actual content of the book still makes sense - a recovery process could actually successfully reconstitute both the Contents and Index (more or less), but  with a hard drive the location of data is dynamic, not fixed in position, as a book is.  Consider files that have been edited and amended over a long period of time.  It is possible that parts of the file will be scattered across more than one drive, which means the method of recovery needs to view pointers to each of the portions of the file which may be on different physical drives.  If the drives were formatted using a non-proprietary structure, then it might be possible to construct the locations of each of the files using a disk sector editor, then pull in each of those sectors in turn to construct each file.  Not a job to be taken lightly.

So basically there is not some program that can do this easily and I would be better off just starting from scratch?

Because there are different ways that these drives can be configured and, in the absence of any assistance from the manufacturer of the drive, I wouldn't think there would be many software vendors up for the job of writing off-the-shelf software for this kind of thing.  How many physical drives are in the device?  What pc motherboard supports the simultaneous attachment of all these drives to it to enable the jigsaw puzzle to be unravelled?  This is the sort of question an off-the-shelf software vendor would ask in order to size up the potential market for such a utility.  So unless you are prepared to follow an arduous list of steps from a specialist who is prepared to share their particular experience with the world at large, or you give the job over to a company like Kroll-OnTrack, I think you might be better starting from scratch.  

Incidentally OnTrack's service is very good, but the way they work is you speak to them first, find out how much it would (non-refundable) cost to send in the drives for evaluation.  If you agree, you send in the drives - they cannot tell you at the outset how much the entire job will cost, but they effectively recover the data and supply you with a complete list of the recovered filenames, together with the price, for your approval.  It is then up to you to decide whether you wish to pay that fee, or not.  If you do, then you get the data on media.  If you don't then all you have lost is the "evaluation" fee.

Does anyone have any recommendations for san device that provideds the capability for mirroring data?

3 days ago I had here a PC with Win XP Pro and the hard drive reported as of "Unknown Format"...
I used "chkdsk" from the WINXP CD and after 2 hours it was fixed ABSOLUTETLY....
SAME with you... Take the hard drives out and repair them if needed to another PC....
The system IS ntfs....

This is a lacie nas device. There is no option to take the hard drives out if I do that voids the warranty.
We purchased this back in November. I opened a ticket with Lacie today.

Notice: kallatech has requested that this question be closed by accepting kallatech's comment #24357016 (0 points) as the solution for the following reason:
Opened ticket with Lacie to return device

My comment "in the absence of any assistance from the manufacturer of the drive" implied that you'd already been through the hoops with LaCie and you were looking for assistance over and above that.

Lacie definitely confirmed that it is hardware failure. They are sending me a box to ship the product back in. This device was configured in a raid 0 setup so my data is lost.

Regarding moorhouselondon's post I did not talk to lacie prior to consulting with the expert's on this site.
My concern was being able to recover the data without too much hastle and without cost.
I appreciate everyone's help and suggestions.
