Hi Cynthia,
Yes, the disc has been cleaned. It is the 4th in a series of 5, all the others have copied but this one just won't read. I put it into the burner and I get Device not ready (Logical unit is in process of becoming ready ) for a long time and then it goes to an I/O error and/or to Device not ready (No reference position found).
I cannot figure out what to do?
Thanks for responding and Happy New Year too!
Sammy
