What file system has been there before? If it is ext2/3 you have
chances to recover a good part of your data. I do not know about
reiserfs/xfs.
Leave the original partition alone. Do not write to it, if you want
more than one try! Copy the partition's contents into a file on
another partition blockwise, then run e2fsck on that image file.
You may need to specify an alternative superblock with the -b
option. When e2fsck thinks, that the filesystem is consistent,
mount the image file with "-t ext2 -o loop". If you're lucky,
you'll end up with a lot of files and directories in "lost+found".
Good Luck, and think about a good backup strategy soon!
