That may represent an issue.
Its entirely possible to recover the deleted files Jeff.. But you have to use specially made software to do so.. And that software isnt free.
Below, is one example of said softwarehttp://www.stellarinfo.com/mac-software/cd-dvd-recovery-mac.php
This can recover files deleted from cd's..
Stellar CD DVD Data Recovery recovers the deleted, lost or inaccessible data from any severely damaged/scratched optical media. Along with single session, multi session data, the software recovers the data written by various packet writing software, such as Drag To Disk, InCD, DLA, Direct CD etc.
This will work to recover the files.. If you have any further questions, please ask.
