rm: cannot remove file: Read-only file system
I have a file on a usb stick which I cannot remove and the following error message shows:
rm: cannot remove `file-name': Read-only file system

The usb stick is mounted as read-only on an Ubuntu system:
Code:
$ mount
/dev/sda1 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
none on /dev type devtmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
/dev/sdb1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,umask=0077,shortname=winnt,utf8)

How can I mount it read and write without having to log in as root?

remove(3C)						   Standard C Library Functions 						remove(3C)

NAME

       remove - remove file

SYNOPSIS

       #include <stdio.h>

       int remove(const char *path);

DESCRIPTION

       The  remove()  function	causes	the file or empty directory whose name is the string pointed to by path to be no longer accessible by that
       name. A subsequent attempt to open that file using that name will fail, unless the file is created anew.

       For files, remove() is identical to  unlink(). For directories, remove() is identical to rmdir().

       See rmdir(2) and unlink(2) for a detailed list of failure conditions.

RETURN VALUES

       Upon successful completion, remove() returns 0. Otherwise, it returns -1 and sets errno to indicate an error.
