After backing up (you didn't before hand? tsk tsk), did you even TRY to 
run chkdsk?  

I assume SSTOR is similiar to STACKER in this aspect:

When a *possibly* corrupt compressed volume, it is mounted read only.  However,
the volume is represented on the host drive as a bid hidden file.  Normally
this file is set with the bits Hidden, Read-only, and System.  SSTOR/STACKER
aware programs (such as DRDOS chkdsk and STACKERS scheck) can play with those
bits and go in and muck around with the file.  Hmm... I would think that 
putting all the functionality of regular chkdsk and sstor-aware chkdsk would
bloat the binary a little bit.  (Or does DRDOS offer 2 version of those 
binaries which would need to be sstor-aware?). 

anyway, my observations,
mrc
