Newfs creates a filesystem that does not pass fsck.

newfs -e 100000000 -b 65536 -f 8192 -g 67108864 -h 16 -i 67108864 -U
 -o space -L 68data /dev/ada2

density reduced from 67108864 to 14860288
/dev/ada2: 2861588.5MB (5860533168 sectors) block size 65536,
 fragment size 8192
 using 789 cylinder groups of 3628.00MB, 58048 blks, 256 inodes.
 with soft updates
super-block backups (for fsck -b #) at:
 256, 7430400, 14860544, 22290688 [ ... ]

Fsck is unhappy:
fsck -fp -t ffs /dev/ufs/68data
/dev/ufs/68data: SUMMARY INFORMATION BAD (SALVAGED)
/dev/ufs/68data: 2 files, 2 used, 366264367 free (23 frags, 45783043 blocks,
 0.0% fragmentation)

Fsck successfully fixed the problem, a second fsck is now happy:
/dev/ufs/68data: 2 files, 2 used, 366264367 free (23 frags, 45783043 blocks,
 0.0% fragmentation)

>How-To-Repeat:
newfs -e 100000000 -b 65536 -f 8192 -g 67108864 -h 16 -i 67108864 -U
 -o space -L 68data /dev/ada2

Adjust partition as needed for your system.

The run fsck and observe complaint.
