Will my Plextor drive make a working back-up of a SafeDisc protected game?
A In short:
-SafeDisc 1: yes
-SafeDisc 2: yes (but only the Plextor PX-W2410A, PX-W4012A/TU, PX-320A, PX-W4824A/TU)
-SafeDisc 2.51.021: yes, although you need software help like CloneCD's 'Amplify Weak Sectors' option.
Longer answer:
There are many SafeDisc versions. The first version (1) is very easily copied by any writer that can write in DAO or SAO-RAW. But then came SafeDisc 2 which defeated many writers, including the current Plex 12x and 16x models. There were some rumours that certain TLA# could do SafeDisc 2 but hard proof was never released. SafeDisc 2 was defeated again with the Plextor 24x models and up. They could make a working back-up of SafeDisc 2 without any additional help of programs like BetaBlocker. Up to SafeDisc 2 version 2.40 everything was fine.. Then the ATIP protection was introduced which included a check to see if the used disc was a CD-Recordable. Not a problem when playing the back-up from a normal CD-Rom/DVD-Rom but you have to use CloneCD's 'Hide CDR Media' to be able to play the game from your writer. Then came SafeDisc 2.51.020 (Tiger Woods) and 2.51.021 (Medal of Honor, GTA3). Some Plextor can copy SafeDisc 2.51.020 just fine but they will all fail with version 2.51.021. But no need to start worrying! CloneCD has introduced 'Amplify Weak Sectors' for these writers to help them make working back-ups. My personal experience is that AWS works very well with the Plextor drives and they now can make a working back-up of SafeDisc 2.51.021. There's no guarantee though! Some people have reported that it still doesn't work.
Q How do I use AWS for my Plextor and when should I use it?
A Because the Plextor writers are 'one-sheep EFM burners' you can leave AWS enabled at all times. Two sheep burners must have it disabled. AWS is enabled by default in CloneCD but you need to check if you're living in the US or Japan if it's enabled. When starting the write process right click on the drive. Choose settings. Can you Select 'Allow AWS'? If so then select it. If not then use this tool to enable it (comments here):
When AWS is allowed for your writer you have to also enabled it in the CloneCD Profiles! The default Game Profile already uses it. You can also download custom Profiles right here. Note that the latest CloneCD version not also has an 'emulate weak sectors' option. This is normally not needed for Plextor drives, they only need amplification to do the job. If that doesn't work you can try emulate but in order to play the emulate back-up you always need to have CloneCD installed and 'Hide CDR Media' enabled (more info)
Q Can the Plextor recorders copy the latest SecuROM copy-protections?
A Well until now there is only one drive that can perfectly copy SecuROM v4.8 and that is the Plextor Premium drive. In combination with the Blindwrite software (4.5.3 or above) the drive is able to make a perfect copy of this protection. For more information see this thread. More information on copying SecuROM with other drive can be found here (using CloneCD) and here (using Alcohol 120%).

uitsnede uit help functie clone cd
Use "Emulate weak sectors", if you don't know if your CD writer supports correct EFM encoding. This feature works with any SAO or DAO CD writer. To use an "emulated" backup, you need an installed CloneCD with "Hide CDR Media" enabled.
Don't forget: With the "Default" Button you can come back to the standard setting at any time.
The options "Amplify weak sectors" and "Emulate weak sectors" are disabled in the United States and Japan.

Ook met SafeDisc v2 beveiligde cd’s zijn te kopiëren. Echter, dit is een stuk moeilijker dan bij SafeDisc v1. Om de zwakke sectoren te kunnen kopiëren is een cd–rewriter met een EFM–encoder nodig. EFM staat voor Eight to Fourteen Modulation. Wat er precies gebeurt is het volgende. Eight to Fourteen wordt tijdens het encoderen gebruikt, omdat de 8–bit ‘magnetische’ byte in overeenstemming moet worden gebracht met een 14–bit ‘optische’ byte. Technisch gezien is deze modulering noodzakelijk om encodering van 2 opeenvolgende 1’en –wat eigenlijk onmogelijk is bij het stelsel van ‘pits en lands’ bij gebruik van 8–bit bytes. In feite worden de veranderingen in reflectiviteit (wanneer de laser langs de reeks van pits en lands gaat) gecodeerd als 1–kanaal bits. Twee opeenvolgende 1’en zijn daaROM niet mogelijk. Bovendien worden de ‘lands’ tussen de 1’en gerepresenteerd door 0–kanaal bits. Gedurende het leesproces demoduleert de interface–card de 14–bit optische code naar de 8–bit code die door de computer wordt gebruikt. De kopie van de met SafeDisc v2 beveiligde CD–ROM moet uiteraard een 1:1–kopie zijn. Deze kopie moet worden gemaakt met CloneCD (of een equivalent) met de optie Amplify Weak Sectors. Deze optie zorgt ervoor dat de zwakke sectoren worden gepatcht (gewijzigd). Dus eigenlijk is de kopie dan geen 1:1–kopie. En zoals eerder gezegd moet de cd–rewriter een EFM–encoder hebben die uniforme bit–patronen correct kan branden. Niet alle branders hebben een EFM–encoder. De meeste branders die gebaseerd zijn op Philips hardware (Philips, Fujitsu/Siemens, Acer) hebben deze EFM–encoder wel. Maar ook zonder een EFM–encoder kan een kopie van de de beveiligde CD–ROM worden gemaakt, los van de kopie die een crack3bevat. Deze kopie (zonder EFM–encoder) is eigenlijk ook een 1:1–kopie, maar toch niet helemaal. Immers, deze kopie werkt niet zonder de emulatie van de SafeDisc v2 beveiliging. Deze emulatie draait op de achtergrond, en ‘simuleert’ de SafeDisc beveiliging. Concreet betekent dit dat het beveiligde programma / spel denkt dat de originele CD–ROM in de drive zit. Een programma waarmee dit kan is DaemonTools.
