I'm not sure if it's available for OpenBSD, but there's dd_rescue as well, which I gather substitutes blocks of zeros for any unreadable sectors.
That would allow you to create an image file with some "holes" filled in with zeros. You then would be able to avoid I/O errors by working against that image file instead of the disk itself. Good luck!

If you are reading this, and are not a recipient of this email, won't you please explain to me how this happened? Luck must be on your side, or perhaps you're just a shoulder-surfer extraordinaire.
