A friend of mine has a DVD with a crack "its a crack straight through it, about two centimeters on each side of the middle circle", he says.

I suggested toothpaste, will anything else work?

No it won't.

Any CD/DVD that is that structurally damaged is not suitable to put into your CD/DVD drive. Putting it risks the disk 'exploding' due to the rotation forces.

This in turn could result in your drive being rendered useless as well as your disk.

Right, knew that. I've heard it happen to friends. Although wikihow suggested tape to fix the foil. Perhaps tape will prevent cracking? – Moshe Feb 12 '10 at 3:06
I highly doubt tape is going to help you once the DVD has a "crack straight through" – Dan McGrath Feb 12 '10 at 3:47
it's not all the way through. Sounds like extreme pressure was applied to the middle of the disc. It probably still is in one piece. – Moshe Feb 12 '10 at 5:01
@Moshe - also, tape will unbalance the CD/DVD, and this is bad too. – Gnoupi Aug 21 '10 at 7:05

Toothpaste will supposedly help a scratched disc by buffing out some of the surface scratches.

I think your friend is out of luck in this case...

Is this real??? – Xavierjazz Feb 12 '10 at 2:45
Yes, toothpaste does work for small scratches, but it won't do anything for a crack through the entire disc. – Sasha Chedygov Feb 12 '10 at 3:04
is there a certain type of toothpaste to apply? – user46941 Aug 21 '10 at 3:38
