I want to make some specefic folders of my 80Gb copied on my 20 Gb. Is there a software that makes a automatic update and make my second drive as a mirror drive.
You can use the Backup feature in Windows XP to accomplish this. That way if your main drive ever goes down you can restore from your backup. There is another way of doing it that I am aware of, but that package costs money.
That will depend on the version of Windows you are currently running. With XP Pro the backup utility is already available since it is installed along with Windows by default. On XP Home edition you have to browse the installation cd until you open up the "D: (cd drive)\ValueAdd\Msft\Ntbackup\" folder and double click on the Ntbackup.msi file to start the installation.
Once installed you simply follow the onscreen instructions for choosing the destination. If you create a custom schedule for automatic backups the system will have to be left running 24/7 until the 20gb drive is full.
