dd if=/dev/ad4 of=/dev/null skip=222342559 bs=512 count=1
dd: /dev/ad4: Input/output error
0+0 records in
0+0 records out
0 bytes transferred in 2.351940 secs (0 bytes/sec)

dd if=/dev/zero of=/dev/ad4 seek=222342559 bs=512 count=1
dd: /dev/ad4: Operation not permitted

Should I do it in single mode?
