check your fat.h and your fsdata

The fatbuf is on the top?

Michael,
Sorry, your latest get_vfatname patch doesn't work either.
FAT16 works perfectly, so the USB code is probably _not_ at fault. I see only problems with FAT32, but only for _some_ long collections of files.
Thus, there may still be a problem with fs/fat/fat.c. Maybe there is something wrong with my copy of fat.c I attached it; Perhaps you can see a problem with it.
Sincerely,
Ken Fuchs

Hi,
Can you try this one?
Revert my last one patch? It change the test code, before the while. I use your script on a Compact Flash and it looks fine for me (under linux).

Check if the entry is a valid dir_slot entry, otherwise it
is a dentry and the
name has to be taken by the get_name function

The scripts in this thread can be used to test the fat32 filesystem. I do some tests using Compact Flash device and this patchs work for me. I would like to know if is a fat layer problem or usb layer problem.
