All methods DBAN includes have been designed to ensure that the data cannot be recovered – at least not with currently available technologies.
Although the documentation inside the disk itself says that "short DoD 5220.22-M" is the default, not "quick erase" (and I could not find what "quick erase" actually is), but with modern hard drives it doesn't really make a difference – overwriting data even once makes it sufficiently hard to recover from such high-density media, as shown by several studies.
Advancing technology has created a situation that has altered previously held best practices regarding magnetic disk type storage media. Basically the change in track density and the related changes in the storage medium have created a situation where the acts of clearing and purging the media have converged. That is, for ATA disk drives manufactured after 2001 (over 15 GB) clearing by overwriting the media once is adequate to protect the media from both keyboard and laboratory attack.

This only applies to data that has been overwritten, so if you managed to interrupt DBAN before it finished its first pass, you might be able to recover what hasn't been touched yet, perhaps using PhotoRec. If the entire disk has been erased, though, you are out of luck.
