I have a NS 4300 4 bay Nas box from Promise.

When i first set the machine up i was looking more for capacity than redundancy so .

At set up i added each drive in independantly 1 drive 1 volume and the default raid setting is Raid 0 .

2 X 1.5 tb and 2 X 1 TB dives in enclosure

So raid zero on each Volume or disk , So not striping across all four disks but each individual disk .

Machine ran well for 1 . 5 years .

Until i upgraded to Win 7 and when connected the Nas Box into my Router network performance dropped drastically , so in my infinite wisdom (after reading various forums ) i reset the machine small hole back of machine to factory reset pushed with pin .

This basically resets the machine not touching the data on the drives.

But when the web window is opened on the device it was asking how the drive layout should be .

And silly me added all four drives as a single volume with raid zero , the machine began to franticalluy spin red a nd green lights , 4 seconds into this realised i may be causing more problems than i bargained for so pullled the power at the back of the machine out .

The drive have now been configured as 1 drive one volume and showing as empty.

I have ran R Studio to analyse the disks and pretty much all the data is still there
No data has been written to the discs , and according to lots of googling the Machine uses EXT3 as its protocol.

Can anyone give me guidance as to how i should start the recovery process and as to what DTI software i should use ?

Thanks in advance
