accidentally deleted raid superblock

because of some (wrong?!?) information i did a 'mdadm --zero-superblock' on all partitions of a raid0 device. unfortunally i can't find a way to recover it. there exists no raidtab and if i tried with 'mdadm -B' a following e2fsck reports many errors, first one all the time in inode 8 (played around with some values for chunk).

so this is the situation:
2 partitions with a raid0 splited ext3 fs but without persistent superblock and without raidtab file.

and i want to:
access the data on the ext3 fs

for linear level of md devices, I rebuild the superblock using mkraid /dev/md0. Consequencely, check md with e2fsck -a /dev/md0
all go fine.
but for your case, I'm doubting. Try at your own risk.
