Putting toothpaste to good use

I read of an interesting way to repair scratched cd. It is very simple. What you need is a tube of toothpaste. Apply the toothpaste over the scratched surface and wipe with a cotton ball until the scratches disappear. After the treatment, the files which cannot be read from your cd will be readable again.

I haven't tried it yet. If you are daring enough, you can try it but I am not responsible for any loss of data on your disc. If it is only one of the backups, then it is no harm trying.

So much for a way to do repair work.
