I don't know enough to comment on the possibility of recovering the entire partition, but I can tell you that it may definitely be possible to recover some individual files based on their magic numbers. Google file carving, magic numbers, etc. You can do it manually with a hex editor -- there also are file carving programs such as foremost/scalpel, but I'm not sure if these have ever been ported to OpenBSD. Of course your first order of business should be to make two copies (one backup, one to experiment on) of the entire hdd this happened with. Use dd to copy the device to a file. Then hash that file and stash the backup copy and the physical hdd somewhere safe and don't touch them. (Disconnect the physical hdd.) Only work with the second copy and compare the hash to see if it's still unaltered -- restore from the backup copy if you mess up. Good luck.
