If you've ever owned a CD or DVD, you've
certainly had to deal with scratched up, unreadable
media. Hardware Secrets has a simple solution:
a scratched CD can be recovered by polishing its
plastic surface. If, after carrying out the
above cleansing, the CD persists in giving
reading errors, just polish the DVD, CD with
toothpaste. That's right, toothpaste. It works
wonders, and you won't spend a fortune buying
professional cleaning kits.
Having learned this trick in college, I can vouch
for it. Don't expect to recover your most damaged
CDs, but you certainly can work a little magic.
