Have you tried fsck? I think that it should mark the sector as bad and  
prevent it's usage...
Hint: _DON'T_ try fsck on a mounted filesystem. Or you'll be another  
author of the unix horror storries. ;-)
Format marks it also as "bad". (But I suppose that you don't want to  
reformat an existing system.)
