Do you mean recovering a file from a damaged filesystem (mounted 
read-only I hope), as in the following command?

  ddrescue /somedir/somefile outfile logfile

Neither ddrescue nor the kernel should segfault in such scenario. What 
versions of ddrescue and OS are you running? What type of filesystem?

They are not so simple. So I would like to be sure that they are useful 
before trying to implemente them.

The '-e' option is already taken since version 0.1 (2004). You are using 
GNU ddrescue. Aren't you?


Best regards,
