Problem - CF card unreadable and corrupted on Mac

My CF card which held the only copy of the files from a shoot this weekend is corrupted... during the first transfer/copy process. It copied a few files over, then stopped. I ejected the card and reinsert, and OSX says the media can't be read and asks if I want to initialize, ignore, or eject. Disk Utility won't even verify the card. It's like the partition is gone. At this point, the card doesn't even get recognized in the camera. So please guide me.
