So I take it these recovered files are locked or something and you can't delete them ?!?
Another thing you may want to try is to run the CHKDSK option.
1) Click on the Start button, then the Run option and type CMD into the run line and click ok or press the enter key.
2) Now use the CHKDSK /F option to fix the partition.
3) It should say something about the volume being locked and would you like to schedule a check during the next reboot cycle. Select y for yes and reboot the machine.
As for these recovered files, can you explain why you can't delete them after you recovered them please
