I archive data files on to CD/RW using Pinnacle Instant CD. When I try to copy a folder on to the CD, I get a message telling me the disc is corrupt. I also cannot now see any of the folders already on the CD, and if I click on the "properties" tab I am told the disc is full (Which it isn't). If I put the CD in the DVD drive I can read all the files on the CD. I would add that I am using the same Drive/software on which the disc was created.
Any suggestions as what is the problem, and how to rescue the disc?
