Recovering a corrupt file

[Marty Billingsley]

Hi --

Any hints on recovering a corrupted Rev file?  We're using 2.6 on Mac OS
10.4.3 and saving files to a Sun workstation that emulates a Mac server by
using a program called xinet.  Anyway, when a student's quota is exceeded
on the server, there is no error message when his RR stack is saved;
however it is corrupt when the student tries to open the stack the next
day.  By corrupt, I mean that RR won't even begin to open it.

One of my students just lost a couple of weeks of work. I can use vi or
emacs to directly edit the RR file if I know what to go and fix.  Any
pointers to documentation that might help me?

Thanks,
  - marty
