My hard disk was working fine. Then suddenly after moving it from another room (it is a laptop).

I did what I found suggested as I feel the HD is a now dead but?? may be I can retrieve some files?

Here's the terminal output:

ronald@ronald-Latitude-D505:~$ dmesg | tail

What does anyone suggest? I read this by installing a new HD and then connecting the "broken" one via a USB as an ext drive.

I suggest booting to a live disc and see if your hard drive is at all accessible.. if it is, backup then replace the HD... If you can pull it out and set it as a secondary HD, or an external HD... You might try the freezer "trick" too.... that may give you enough time to start recovering data from the HD... Other then that you can take it to a professional data recovery place and see if they can help, but that is going to be expensive...

Hope this helps, good luck!
