        <p>SMART provides statistics of disk firmware, this system
        handle errors has their occur. Badblocks detect bad blocks
        by writing and reading from disk in a destructive test.
        Example of how to view SMART statistics of a disk;</p>

        <pre>
        # smartctl -t long /dev/sdb1
        # smartctl -a /dev/sdb1 | less
        </pre>

        <p>Search for bad blocks using
        <a href="https://wiki.archlinux.org/index.php/Badblocks">non destructive test;</a></p>

        <pre>
        # badblocks -nsv /dev/sdb1
        </pre>

        <h2 id="mv">2. Moving data</h2>

        <p>Temp partition with 20M-50M;</p>

        <pre>
        (parted) mkpart primary ext4 4000MiB 4050MiB
        </pre>

        <p>Ports partition with 120G allows to host sources, package
        backups and ports;</p>

        <pre>
        (parted) mkpart primary ext4 192000MiB 312000MiB
        </pre>


        <p>Reboot into single-user mode where services aren't started and networking is offline.<p>

        <pre>
        # init 1
        </pre>

        <p>Copy the data:</p>

        <pre>
        # cp -apx /srv/* /mnt/srv
        </pre>

        <p>Rename directory, for later backup;</p>

        <pre>
        # mv /srv /srv.old
        # mkdir /srv
        </pre>

        <p>Edit the <a href="../conf/etc/fstab">/etc/fstab</a>file:</p>

        <pre>
        # Temporary Data /tmp
        UUID=50bf6e55-6461-4dd4-b315-65b53cac0995 /tmp            ext4    defaults,nodev,nosuid,noexec	0	0

        # Server Data /srv
        UUID=6fadcb98-e442-4af7-a5f2-1ddb6100a8c4 /srv            ext4    defaults        0       2
