Put a space between the o and the g in the term -ogid=1000. It should read -o gid=1000.
Nevertheless this still won't work because a normally privileged user cannot give himself rights, which is implied in the -o gid=1000. The mount command looks in the /etc/fstab file to find out whether the normal user account has the right to mount the drive. You can use the sudo command to execute a command as root.
When it asks you for a password you give it the password of the normal user account, not the root password. The normal user account has got to be listed in the /etc/sudoers file.
I don't think that there is a portable way for normally privileged users to mount a file system without doing something to the operating system first. Whether you have to edit a line in /etc/fstab or whether you add the user account in /etc/sudoers you still have to do something to a normal system configuration before a normal user account can mount a file system.
