Bad block -> file mapping

[M. Warner Losh]

I have a hard disk that's been in service a long time.  I recently
installed the SMART monitoring tools.  On occasion, I get reports of
LBAs it can't read.  I'd like to map the LBA to an actual file in the
file system, if possible.  Does anybody have any tools that can help
me with this?

I know I need to get a new disk.  In the mean time, I need to cope
with these errors in a sane manner...

P.S.  Here's a sample report:
