we are using lot of slim CD/DVD R/RW, the lense was damaged because of handling. what are all the pre cautions or warning msg i need. pls. clarify my doubts.

This may give away too much about my submission, but hey, it's worth a shot. My DoAdd function currently weighs in around 3.66 GB. I haven't written the rest yet - my fingers are bloody and raw. I've gone through 18 keyboards. With some good compression, I should be able to get it down to about one DVD...
