This tool is broken after block device is disappeared from FreeBSD.
I corrected it,but I don't have code for now.(It is at my desktop computer,
 50km far from here.)
To use this tool,
# dd if=/dev/${DEV} of=/dev/null 
(${DEV} is the device where the bad sector exiist)
and if bad secter exist, it stops at the block count of the bad sector.
${AAAA}+0 records in
${AAAA}+0 records out
${BBBB} bytes transferred in ${XX} secs (${YY} bytes/sec)
then use 
# badsect /${FS}/BAD ${AAAA}
in singule user mode with the ${FS} mounted.
Then unmount the ${FS} and use fsck.
