                UPDATE:  This bug was recorded using the PIC32 Ethernet
                Starter kit with a RAM disk (that board has no SD card slot).
                Howevever, using the USB mass storage device with the
                Mikroelektronika using a real SD card, there is no such

+               shows problems again.  I think that there are some subtle

   Status:      Open
   Priority:    Originally, High BUT reduced to very Low based on the
