I would also ask what platform are you using (Linux, Windows, MacOS)  
and what file system contains your data file: local hard disk, network  
file - in which case what protocol?  I ask because there was a recent  
report of what I think might be a similar problem, when using a SAMBA  
share, from a particular server vendor.
