Thanks Mikkel, but there wasn't an error. There wasn't any effect also. 
I have tried several times with -F 16, because fsck reported:
First FAT starts at byte 512 (sector 1)
        2 FATs, 16 bit entries
Then I have tried with -F 32, again with no success. As I sad mkdosfs 
didn't report any error, however in dmesg I saw several resets of the 
device during the mkdosfs process. After that when I remount the player 
all the files are still there, and the player itself again doesn't see them.
