Reformat means completely erase, then reallocate the blocks of the drive for new use–which pretty much kills any chance of file recovery.

If you're simply trying to repartition the drive, you should be able to use Apple's Disk Utility app to completely reformat the drive and re-partition it. Notice I didn't say "restore." You aren't going to be able to restore anything, because there's nothing there to restore.

I think that's a full wipe. A quick wipe will just delete the directory. Some scavenging apps may be able to recover some files... but it's hit and miss.
Disk Warrior used to be the tool for scavenging a drive without a directory.
