In the ntfs case when properly implemented finding a bad sector will just 
add the cluster in which it lies to $BadClus and remap it on disk and write 
it out again, no need to give errors / exceptions. But I doubt you would 
ever see a bad sector on a modern disk... More likely the disk will die 
altogether before that.

Thanks, but we would like to keep libntfs as C for now.

Why can't libparted recognize error return values from libntfs and do 
whatever it likes with them? You can then use your exceptions once the 
error code path has left libntfs and has come back to libparted... You can 
then always retry the libntfs call if you were so inclined.
