Recovering Data from CDR previously burned sessions
 

Are there any good utilities out there for linux that allow you to view data from previously burned sessions on CDRs??? Reason I ask is I have a CDR that I had previously burned to and when I used the GnomeToaster beta 1.6, to add some more files to it, now I can no longer access the previously burned CD data. Toaster doesn't seem to have any tools to allow you to locate older data.
