is it possible to make an exact replica of a c.d. even its volume label and volume serial number are the same?

NO Volume serial number is unique

Thanks. I know its unique too, following the line that duplication of a CD is a copy and burn process or read from 1 CD and write/burn to another CD.

forgive me for my ignorance, i know this is trivial, just want to know and learn. but, how do they mass produce a software cd or for that matter any cd?

because in my OWN simple thinking, in mass production, you have the original cd that is used as MASTER CD, a CD reproduction machine, and then copies are made from "raw materials molded as" copy CD's. by this process, everything are copied, exactly from the source, even the disk label and volume serial number. is this true, or am i thinking dumb? hope you can enlighten me.

unfortunately, i cannot verify if there are two CD's exactly the same (label and serial number) because i dont have 2 CD's with the same title...

I really don't know enough about it to be very helpful. Have you done any searches on google?

It even discusses the labels and how they're made.

thanks junker. i checked the link. Unfortunately it only discussed the difference of duplication and replication process. it did not answer whether a replication process makes an exact replica of the master-cd, thereby replicating even its volume label and volume serial number.

thanks dave. i find the link you recommended quite helpful, but i think the serial number being referred to in the posts is the serial number of the xp software, and not the volume serial number of the CD which you will see when you do a DIR command on the CD.

will check further

Can someone tell me if all XP cd's have their own unique id number?
No, they don't. If they did, they'd have to cost a lot more.
OK, then this is where I get confused.

If the cd is installed with its serial number (the same serial number that
thousands of others have) and you use that same cd with its same serial
number and illegally install it into 10 other pc's.

How does Microsoft know this and deny you your Windows updates?

You may find that the Software has:
Serial number of: 552XX-XX3-02434XX-222XX
Product Key: XP88T-R4488-XQH88-XY988H-G8867
