AFAIK, to use bad144, you need a disk drive that does not handle bad blocks by itself. And vice versa. Then, you need to disklabel the drive (or, more precisely, the slice) such that it uses bad144 mapping. This means that your 'c' partition has at least enough room at the end to hold all bad blocks plus the bad block data structure (I think), which amounts to 126 sectors (or so). Traditionally, you sacrifice the last cylinder of the drive (slice) for this. Thus, it is not possible to use 'c' as a filesystem or swap partition if you bad144 it, and the last handful of sectors want to be left alone on 'c'. You don't want to use bad144 for your setup.
