"Norton Utilities" for ubuntu

[eyore15 User]

I had occasion today to over-write a file I really needed.  I thought how 
convenient it would be to have file recovery utility like Norton Rescue.  
I'm pretty sure there is something out there, I just don't know what to 
call it.  Ideally it would be in the Synaptic repositories.

Can you offer me any hope?

I'm running Ubuntu 9.04 on a PS4HT at 3.2.

tnx
