Now I can't update my bootblocks to new ones using 'disklabel -B da0s1', checklabel() disklabel function return error preventing actual write with following diagnostic: partition b: partition extends past end of unit partition c: partition extends past end of unit Warning, partition c doesn't start at 0! Warning, An incorrect partition c may cause problems for standard system utilities Warning, partition d: size 0, but offset 32 Warning, partition e: size 0, but offset 32 Warning, partition f: size 0, but offset 32 Warning, partition g: size 0, but offset 32 Warning, partition h: size 0, but offset 32 In fact, this is exact the same diagnostic as from 'disklabel -r da0s1': # /dev/da0s1c: type: SCSI disk: da0s1 label: flags: bytes/sector: 512 sectors/track: 32 tracks/cylinder: 64 sectors/cylinder: 2048 cylinders: 17500 sectors/unit: 35842016 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 bps/cpg] a: 34611200 32 4.2BSD 2048 16384 64 # (Cyl. 0*- 16900) b: 1230816 34611232 swap # (Cyl. 16900*- 17500*) c: 35842016 32 unused 0 0 # (Cyl. 0*- 17500*) partition b: partition extends past end of unit partition c: partition extends past end of unit Warning, partition c doesn't start at 0!
