Mike,

I believe that your problem does sound like a McIDAS file was still
open. Even if the file is deleted, the OS won't get the space back 
if the program still has the file handle open and is writing to it.

Stopping LDM likely caused the xcd log file to close, so maybe that was 
the culprit.

Tom is out of the office currently, but can probably recreate your solution 
and future avoidance when he returns.
