permision denied to write in a partition mounted at startup

[manou]

Hi, I have a fat32 partition that i mount at the startup since i have
put
/dev/hda5 vfat defaults 0 0
and i've tried also with
/dev/hda5 vfat user,auto,rw

at /etc/fstab file.

when i log in as a normal user i can't write to this particion because
only root has permision, but i want everybody can write.

anybody can tell me how can i do this ?

thanks in advance.
