Repair a ProDOS disk?

[knowles@sampson.inmet (Dick Knowles)]

I'm wondering if anyone knows how I might try to recover/repair a
disk.  My daughter was using Appleworks to write a college paper when
disk activity became impossible.  I've experienced this recently after
the //e has been on for a long time.  Something is overheating, and it
works after it's powered off and cools.  But this time, her paper was
on the desktop only.  When she couldn't save it, I tried to print it,
which gave it a permanent problem, since the program disk was no more
accessible than the data disk.  In my fiddling, hoping to save some of
her work before powering down, I managed to screw up something.  Now
that everything is cool and working again, when I try to read her data
disk, Appleworks says "Getting errors trying to read directory".  So I
must have managed to clobber the directory.  Can someone tell me how I
might fix it, or she loses a lot of work on that disk.  I do have a
DOS disk sector editor.  Thanks for any help!
