No:

sd0 at scsibus0 target 1 lun 0: <IBM, DGHS09U, 03E0> disk fixed
sd0: 8678 MB, 8152 cyl, 10 head, 218 sec, 512 bytes/sect x 17774160 sectors
sd0: sync (50.00ns offset 15), 16-bit (40.000MB/s) transfers, tagged queuei=
ng

# dd of=3D/dev/null if=3D/dev/rsd0c bs=3D128k
69428+3 records in
69428+3 records out
9100369920 bytes transferred in 748.450 secs (12158955 bytes/sec)

9100369920 bytes are exactely 17774160 512 byte blocks.

Also note that the problem occures when newfs(8)ing sd0a:
# newfs /dev/rsd0a
/dev/rsd0a: 128.8MB (263780 sectors) block size 8192, fragment size 1024
        using 4 cylinder groups of 32.20MB, 4122 blks, 7936 inodes.
wtfs: write error for sector 263779: Undefined error: 0

This is strange. :-?
