After fdisk and some partition definitions I am getting using "disklabel -r sd1": # /dev/rsd1c: type: SCSI disk: sd1s1 label: flags: bytes/sector: 512 sectors/track: 32 tracks/cylinder: 64 sectors/cylinder: 2048 cylinders: 80 sectors/unit: 165856 rpm: 0 interleave: 0 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 145856 20000 4.2BSD 0 0 0 # (Cyl. 9*- 80*) b: 20000 0 swap # (Cyl. 0 - 9*) c: 165856 0 unused 0 0 # (Cyl. 0 - 80*) I have some questions (I am trying to understand this all): 1. If I exit, disklabel is complaining about rpm and interleave. Can I change them to whatever I like (that is: are they actually used?)? 2. Why 8 partitions? There is only 3 (I have 8 on sd0) 3. If I change the order to # size offset fstype [fsize bsize bps/cpg] a: 145856 0 4.2BSD 0 0 0 # (Cyl. 9*- 80*) b: 20000 145856 swap # (Cyl. 0 - 9*) c: 165856 0 unused 0 0 # (Cyl. 0 - 80*) Mount does not accpet it, "/dev/sd1a on /mnt: Incorrect super block.".
