permissions problem

[Gerhard Magnus]

I'm running FC5 and gnome on a machine dual booting with Windows and
would like to read from/write to a Windows vfat partition.  I've added
this line to /etc/fstab:

/dev/sdb1   /mnt/win   vfat    rw,noatime,uid=500,gid=500,user   0 0

Then, also as root:

mkdir /mnt/win
chmod 777 /mnt/win

In linux, I can now read from the /mnt/win directory but can't write to
it without root privileges.  How should I set the privileges on this
directory so that I can write to it as a user?  Are the mount parameters
in fstab correct?

Thanks for the help!  --Jerry
