[SWLUG] mystery file permissions

[bascule]

i have an mp3 directory on a vfat partition mounted at boot with the 
following fstab entry
/dev/hda6 on /mnt/drivef type vfat 
(rw,umask=0,iocharset=iso8859-1,codepage=850)

i've been editing tags as an ordinary user and discovered that some files are 
denied editing access as follows:

-rwxrwxrwx    1 root     root      3610881 Sep 21 21:18 12_pulp - 
mis-shapes.mp3*
-rwxrwxrwx    1 root     root      3526890 Sep 21 21:18 13_ocean colour scene 
-
travellers tune.mp3*
-r-xr-xr-x    1 root     root      4107283 Sep 23  2000 14_sheryl crow - 
everyday is a winding road.mp3*
-r-xr-xr-x    1 root     root      3531754 Sep 23  2000 15_james - shes a 
star.mp3*

how can this be as these files are on a vfat partition? one or the other fair 
enough - depending on umask etc. but both sets of permssions, in the same 
directory?

any ideas?
