Run sudo testdisk /dev/<your disk>. As soon as you're in testdisk select 
the disk and press <enter> to proceed. It should be on [Intel] so press 
<enter> again. Select [Analyze] and press <enter>, select [Quick Search] 
and press <enter>,  if it asks if your partition was created under Vista 
say 'N'. If it takes more than a few seconds stop the search and select 
the partition that your data is on.  Press <p> to list the files and <c> 
to copy them. You'll be asked for a location to store the files. 
Navigate to the folder where you want the recovered files stored and 
press <y>.

The same procedure works for undeleting/listing files in if you select 
[Advanced] instead of [Analyse]. Follow the steps from "and press <c> to 
copy them" above.

On that link I gave you you'll see a link to GNU Ddrescue. Try not to 
use dd.
