I would be interested to know if you could somehow get a PC to access the c=
ard in a similar manner to how you have been testing it with the PIC, to se=
e if it falls over, or does some other form of recovery action to re-read t=
he file (how you would detect this I don't know).

I am wondering if there is an error in the FTL SPI code that hasn't been pr=
operly debugged, but the 4 bit parallel mode works fine.

Oh for a way to learn about the 4 bit mode without having to join the SD Ca=
rd organisation ...

P.S. has anyone thought about if the 4 bit mode that is announced as a feat=
ure of the newer PIC32 devices is designed to interface SD cards? It was my=
 immediate thought when I saw it in the data sheet, but don't know if there=
 is any working silicon yet.
