Bad Sector in CD?

You mean for disposing of it? Run the edge of it through a good solid paper shredder(be careful to keep your fingers). Otherwise if you are trying to use it yourself how would you read it with a bad sector?

No No, i mean that there are some software in market by the help of which we can create bad sector in CD, so that nobody can copy that CD.
But we can use that CD as well after cdreating bad sector with the help of that software.
So can you know about these types of software.....?
Or is there any technology by the help of which i can do this.
Kindly reply me..........

No No, i mean that there are some software in market by the help of which we can create bad sector in CD, so that nobody can copy that CD.

No, wasn't aware of that sorry. I thought you were trying to get rid of some confidential CDs.
Maybe ask the men and women of the hardware forums.

Ha Ha....:)
No I was not trying to get rid of some confidential CDs.
