If you get something similar like "Disk /dev/dm-0 doesn't contain a valid partition table" or "mount: unknown file system type 'lvm2pv'" its because you have LVM's that 'fdisk' can not recognize, (or something like that) its nothing to worry about if you get that when executed the Diskmounter.sh script.
''So the steps in a logical order:''
<ul><li>connect your disk</li>
<li>download the[http://wiki.amahi.org/images/c/c6/Diskmounter.sh diskmounter] script</li>
<li>run the following command on the script: root@localhost # chmod 755 Diskmounter.sh</li>
<li>run the script: root@localhost # ./Diskmounter.sh</li>
