It appears to see the label (ie: slice "e" shows up as type "BSD", which is where I'd expect the slice to map) but an attempt to fsck it blows sky-high, and an attempt to mount -ro panics instantly. A "disksetup" (their equivalent to disklabel) gives this: type: SCSI disk: SEAGATE ST31200N label: flags: bytes/sector: 512 sectors/track: 64 tracks/cylinder: 8 sectors/cylinder: 512 cylinders: 4026 sectors/unit: 2061108 replacement sectors/track: 0 replacement sectors/cylinder: 0 alternate cylinders: 0 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize cpg] a: 65536 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 127) b: 256000 65536 swap # (Cyl. 128 - 627) c: 2061108 0 unused 0 0 # (Cyl. 0 - 4025*) h: 1739572 321536 4.2BSD 1024 8192 16 # (Cyl. 628 - 4025*) Which looks pretty normal.
