I recorded files on a CDR. Later on, when tried to use it... it stated that there were files present, but they couldn't be accessed. I assumed only the file system was intact, because you can see all the files.. you just couldn't run them or view them. Later on, I got Roxio software and attempted a CD repair. It repaired the CD (I think it was a reformat)... but this time it said only 300MB of free space was available (out of 650MB). The CD no longer displayed any files. How stupid can I get? I erased over 350MB of data. But I became perplexed because how can you get 300MB of free space out of a full 650MB CDR that's written to the MAX? So I decide to write over the 300MB of free space to see if it was possible. It was. A few weeks later I decide to view the damaged CD and low and behold... I saw all the original files displayed. Of course I must be dreaming. I think I finally woke up when all the files sucessfully transfered to my hard drive. I really don't know what happened, but I'm just happy to get the original files back.
