[QUOTE=silencehjzh;2228101]I want to achieve the following result: The CD-R seems as usual, but the content of it can not be seen for ever, for any one. This means destroying the CD-R without trace left![/QUOTE]
AFAIK there is no software-tool that allows to do this with any generic drive (writer). But there exist standalone hardware and hardware-software combinations that allow for what you want:
The entire disc is wiped.
Plextor drive models 755, 760 and Premium2 also have that functionality built in. It is operated via the Plextools software. For example see spec sheet:
This solution allows for overwriting the lead-in only (faster) of for an entire wipe.
Also newer LiteON drives (IHAS / IHAP Models) have offer this function too. It is operated via a LiteON provided utility. It’s very similar to what is offered on the Plextor writers.
