Hello Richard,

I correct this problem in my FreeBSD using the badsect program
When the error occurs the system display on the console: FSB NNNNNNNNN 
where NNN is the sector number in error.
1) make a /BAD directory in the file system in error say: /usr/BAD
2) run badsect /usr/BAD NNNN NNNNN NNNN...
3) boot the machine with -s option.
4) run fsck /dev/rwdxx (xx) as indicated in the badsect output
5) answer to the fsck (y or n) according. (preserve BAD..., no remove 
BAD, remove file...)
6) quit shell and let the system reboot.
7) recover deleted files listed by fsck. (from the cdrom for example).

That's it .
