you'll often get the 'device is busy' message When showing all available drives, choose one, which will be recovering lost files. Unmounting the drive on a live system can be tricky. Note: extundelete requires you to unmount your drive to work properly (this is a good idea to do ASAP anyway, to avoid potentially overwriting the hopefully-recoverable bytes in the deleted files).

Extundelete is really great if your file system is ext3 or ext4.
