Can i use testdisk/photorec in this case , and how ?

[Teejoo]

Hello folks,

I apoligize in advanced, for i came across a link to this free soft that came highly recomended. I am not a specialist in any of these matters , so please dont shoot me is i ask wrong stuff Feel free to correct me pls !
Question :
Can I , and how if yes, use testdisk/photorec to "unformat" a 10TB RAID0 array of 5 x 2TB, on a linux ArchBang system, formated in ext4. The array was formated unexpectedly. Is there any way i can recover the data usingtestdesk/photorec, without having to provide an other 10TB of diskspace to recover these files. We just dont have an other set of disks available.
I gave both a try already, but i am unsure on the to follow steps.
I can already say that testdisk recognizes each disk individualy, and does see the array also.

Many thax in advanced,
Teejoo

You can use PhotoRec on the array but you will need 10 TB to store the recovered files.
You must not attempt to write the recovered files on the source.
