Not really. I've done some data recovery on ext3 and other filesystems. Since 
you've got a new format, you can't do anything to recover the journal. Your 
only hope is to read all the data on the drive for recognisable files and 
extract them. There are several tools designed for this, and are good at 
recovering things like images, text, mp3s, and so on.

See the "photorec" command in the "testdisk" package for your best chance. It 
will take a long time, and you'll need another drive or partition to dump to.

Regards,
Tyler
