In the function, it is assumed that sizeof(name) will have the value 8, but this is not the case (at least not for the compiler I use and I guess not according to ANSI C). This causes "long filename checksum errors" for each fat file listed or written.

Please post it with a Signed-off-by line for review on the list, thanks!
