why cant i backup the sims

[Einstein]

Hello there,
The Sims has SafeDisc 1 protection, that is why u r having problems copying with Nero.
Use CloneCD with the Fast Error Skip setting ticked, & within the Fast Error Skip settings, set the Read Retries to 0, & the Error Correction to Software.
This should give u a perfect 1:1 copy of the Sims.
Get yourself a copy of ClonyXL to identify the protection on cd's & it will give u the settings within CloneCD to copy them.
You can get this from ####://www.cdmediaworld.com/hardware/cdrom/cd_utils.shtml
in the CD-Protection Utilities section called Clony.

Hope it helps.
