The CD\DVD page of the Options window (accessible from the Tools, Options menu item) contains the settings of the CD or DVD burners.
Engine
Use primary burning engine - Selected by default. Backup4all uses an internal burning engine to write CD/DVDs. It has integrated two burning engines in case that one of them does not recognize your burner. If your CD/DVD burner is recognized and you have no problem at all backing up to CD/DVD then you don't have to change this option.
Use secondary burning engine - If you have problems backing up to CD/DVD or your burner is not recognized when using the primary burning engine, select this option to make Backup4all switch to the secondary integrated burning engine. Also, if you are making mirror backups, it is recommended to choose this secondary burning engine even if the burner is recognized when using primary burning engine (speeds up the backup process, but only for mirror backups).
| · | Burn CD/DVD using internal ASPI - If checked Backup4all will use its own, built in ASPI layer to burn CDs or DVDs. If not checked, it will use the ASPI layer from the system32 folder of Windows (WNASPI.dll). If you experience problems writing to CD/DVD and these were not solved when switching from the primary burning engine to the secondary one, you should check this option. By default this option is checked and it's available only when Use secondary burning engine is selected. |
| · | External ASPI path - Usually the ASPI layer is located in C:\WINNT\system32\. If it's located in a different directory use the Browse  option to select it. |
Other
Load CD/DVD before backup - If checked, the CD or DVD media is loaded before the execution of a backup. This option is useful when the CD\DVD was previously ejected by another process.
Eject CD/DVD after backup - If checked, the CD or DVD media is ejected, but not reloaded after burning process is finished. By default this option is not checked.
