I think the reason is that CWSDPMI opens a swap file to support virtual
memory, and CHKDSK complains because the directory entry for the swap file
isn't updated until you exit your program (at which point CWSDPMI closes
and deletes the swap file). 

It is generally not recommended to run CHKDSK while another program has 
some files open.  If you try that from Windows' DOS box, for example, you 
will also see error messages from CHKDSK.

You didn't explain why do you need to run CHKDSK in the middle of your 
program.  So it's hard to answer this question.
