Thank you John. The thing is my data was not overwritten, corrupted, etc. Some was, but I know which parts. Basically, I just cleared the file system designation. So if a file is 64K, does the first 32K on drive 1 contain the first half of the file and the first 32K on drive 2 contain the second half, or are the 32 size chunks on random locations?
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.
Let me expand by saying.
1 make sure the partition table is restored to it's exact prior setup.
2 verify the md raid metadata at the end of the raid partition is ok. Need to research that one.
3 reassemble the raid0
4 make a copy of the raid device
5 use recovery tools on the copy to retrieve as much data as you can
