With What software can i create a write protected cd,and how?

WHAT???

Once a CD-R is burned, it can no longer be re-burned. A CD-RW can still be Erased and Re-burned, though. However, a multi-session can have more data burned onto it, in which case don't use multisession when burning to prevent it.

Do you mean Copy-Protect it, to keep it from being copied?

yes mean copy protect.

Explaination of Playstation Game Copy Protection.

Sony has a very effective way of protecting their disks,

but it requires a hardware patch for both the reading and writing of the disk.

One of the sectors is 1024 bytes long (2 sectors joined together)

The hardware reads this sector and the string "Sony Corporation Of America"

is spanned across the break.

The hardware reads this sector and if the string is corrupted(copied disk) it rejects it.

To recreate this, you must rewrite the hardware code for the burner (NOT EASY AT ALL)

and even then, the disk can be copied and used unless similar code checks for this sector.

This is just one example, there are many others but the jist is that the Burner Hardware Code

will need to be tampered with in order to create the disks.

OK, FWIW....
