Help with USB directory permissions

I'd like to set a USB device to mount with write permissions for all users and groups. Below you can see chmod doesn't affect the change. What am I missing?

Code:

[user@localhost disk-1]$ id
uid=500(user) gid=500(user) groups=10(wheel),500(user)
[user@localhost disk-1]$ cat /etc/mtab 
/dev/sda1 / ext2 rw 0 0
none /dev/pts devpts rw,gid=5,mode=620 0 0
none /dev/shm tmpfs rw 0 0
none /sys sysfs rw 0 0
none /mnt/home aufs rw,si=f39d22c0,xino=/home/user/.aufs.xino,create=mfs,dirs=/home/user=rw 0 0
/dev/mmcblk0p1 /media/disk vfat rw,nosuid,nodev,uhelper=hal,utf8,shortname=winnt,uid=500 0 0
/dev/sdb1 /media/WD\040Passport vfat rw,nosuid,nodev,uhelper=hal,utf8,shortname=winnt,uid=500 0 0
/dev/sdc /media/disk-1 vfat rw,nosuid,nodev,uhelper=hal,utf8,shortname=winnt,uid=500 0 0
[user@localhost disk-1]$ cat /etc/fstab 
/dev/sda1          /                  ext2          defaults,noatime        1 1
none               /dev/pts           devpts        gid=5,mode=620         0 0
none               /dev/shm           tmpfs         defaults               0 0
none               /proc              proc          defaults               0 0
none               /sys               sysfs         defaults               0 0
#none               /tmp               tmpfs         defaults               0 0
/dev/sda2          swap               swap         defaults               0 0

You are looking at a FAT filesystem on that stick.
Afaik there is no such thing as permissions in FAT.

HTH, --Japser.

 

You're right of course. I have a program that doesn't write to the drive. I'll have to think on that problem a bit more...
