I would like to know if it's possible to create an unreadable CD, without phisical scrathes obviously.
If you put the CD into the drive it will look like it doesn't work or is erronous.
I've been thinking about create an error during the burning on Nero? Maybe a cyclic redundancy error. But How?
Or even encrypt the data with a password (perhaps CryptCD can help)?
Something that becomes inaccessible the content of the CD...
