Formatted/repartitioned wrong disk, arrgh!

[Jesper Jensen <linux-ext4_mailinglist@elector.dk>]

First of all I know this isn't a development or bug related question, 
but I'm running out of ideas on how to rescue my files, so I hope you 
guys can bare with me.

Yesterday I accidentally did a repartition ad and mkfs.ext4 on the wrong 
data disk, ARRGH! I thought it was an empty disk, but nooo it was one 
containing a lot of data that I don't really have a backup of anywhere. :-(

I've tried various fsck -f -b <backup superblocks> but it looks like I 
might have made a royal fuckup and overwritten/erased every single 
backup superblock. :-(

As far as I recall the first time I ran fsck it said something about the 
blocks being empty and asked me to accept a bunch of times (eventually 
ended up using the -p option).

I have also tried tools like magicrescue and foremost to recover my 
files, but no such luck.

Can you guys recommend a good way to recover the files?

Jesper
