I guess you're using NTFS. In your case I would try to isolate the issue somehow. For example try to disable the swap file, disk caching, etc. It's nasty if you don't know how to reproduce the issue. Maybe you could experiment with a cloned partition on another machine. Or the disk in another machine. I would like to know the causes of this, so if you find out anything please post it.
