What, exactly, do you mean by "volume formats"?
What type of media? Some USB-to-[PS]ATA bridges have bugs
(or just plain brain damage) and sector(s) are missing.
This can prevent the OS from finding the partitioning info.
This can be worked around by hacking the kernel, but probably
doesn't qualify as the "least amount of wasted effort/time"
you are seeking.
What type of partitioning? BSD disklabel? MBR? GPT? ...
What filesystem?
I have vanilla sata disks with a NetBSD mbr, and NetBSD 4.0
and 5.0.1 partitions ("slices" if you prefer), FFS with softdep.
FreeBSD/amd64 6.x, 7.x and 8.x mount and read these partitions fine.
NetBSD 6.0 and newer would not have softdep. FreeBSD 10.1 is broken.
NetBSD partitions on gpt disks also mount and read fine under
FreeBSD.
