- In my case, HPFS is faster accessing many small files, slower accessing
- one file, and much less secure than FAT, at least with the current
- drivers. From time to time one of my files on the HPFS partition gets
- corrupted (chkdsk /f does not detect it), and any access to that file
- freezes the system. The current HPFS fixes helped a little bit, but not quite.
