I've already cloned the entire thing to the scratch drive. I'd just rather not rewrite it in its entirety again. How much of the disk will I need to rewrite to get the partition table back to its original state if my attempts are unsuccessful? IIRC, bits are written to the end of the disk as well, so I'm not sure how to do it with dd(1), though I'm sure it can be done. > gpart backup produces plain text that can be manually created.
