$df /dev/hda7 -h -T
Filesystem    Type    Size  Used Avail Use%  Mounted on
/dev/hda7     vfat    126G   35G   91G  28%  /mnt/prtg

$strace df /dev/hda7 -h -T 2>&1 | grep statfs
statfs("/mnt/prtg", {f_type="MSDOS_SUPER_MAGIC", f_bsize=32768,
f_blocks=4120920, f_bfree=2971459, f_files=0, f_ffree=0, f_namelen=260})
= 0

$uname -a
Linux big-gnu 2.4.25-big-gnu #5 SMP Fri Mar 26 20:02:27 CET 2004 i686

I hope this will help,
