[ubuntu] recover ext4 file structure after quick format

view story

http://ubuntuforums.org – I was installing a new hardrive and formatted the wrong 2TB drive. It was originally all ext4 and I deleted that partition and formated 1.9TB ext4 and the last GB Swap. Nothing has been written to either partition. Is it possible to recover the folder structure or at least the file names? PhotoRec started to recover files but that won't work. I need at least the file names, preferably the folder structure . If this has been answered, sorry. Please point me in the direction of the answer. Thanks (Hardware)
