Trying to restich a broken RAID0 is going to be difficult. Question is  
is the md raid metadata ok, if it isn't then you are hosed. Make sure  
the metadata, usually stored in the last 64k+ of the partition is ok  
then see if you can reassemble the array, then try using a disk or  
file system rescue utility on a copy of the md raid block device and  
see what data you can recover.
