write permissions for mounted ext3 filesystem

In words of an experienced user at Suse forum

> The permissions aren't set to the user when it's mounted, that is
> correct. ext3 stores the user permissions internally. You need to
> change the permissions of the disk when it's mounted, the same way
> you would any other file or directory. So, when the disk is
> mounted, do
> chmod 777 /mnt/fwdisk1/
> Note that the disk *has* to be mounted when you run this, otherwise
> it won't work
