PLease help me reconstruct my array (RAID 5 ) if possible.

As I wrote in another thread, because of hardware failure my RAID 5 array crashed. After som rebuilding the array crashed again. I have built the array again
with the right settings, but it has rebuilt and data is gone - I can not find any EXT3 partition on the array anymore. Is there any way for me to find back to my data?
