Major screw up I did
 

Is there any way to retreive data that was on a partition I deleted?

I have not formated that partition yet.

i think you might be able to get away with remaking the partition as you had it, and it should work. cos as partitions operate pretty much independently to the FAT, simply registering the partition at EXACTLY the same size and location as before, it should be able to pick up the old FAT automatically. like i had an ext3 partition listed as a fat32 for agesm, and neither of them gave a toss....
