Thank you.  This is exactly the information I wanted.

The problem is that my failed partition is ReiserFS.  The icheck and
ncheck commands are part of debugfs, which is ext2/ext3-specific, and
all I can find online is other people complaining that ReiserFS
doesn't have an equivalent command.  There doesn't appear to be any
way to get ReiserFS to tell what files are on what sectors.

However, ddrsummarize.pl (thank you Dave!) shows that the 1688 bad
sectors mentioned in the logfile actually translates to less than 1MB
of data lost.  This makes me happy (I can deal with 800kB of lost
data, out of 111GB) and annoyed (all this trouble over only 800kB?).
I will just restore the drive and find out through trial and error
what does and doesn't work.

(I do intend to keep the logfile and other data I've accumulated, just
in case I hear of a way to do this down the road a bit.)
