How to burn disk image on CD or DVD media
To burn a CD/DVD image file to a target CD/DVD media:
1. Open the disk image file.
NOTE: Burning of multisession CD images is currently not supported.
Undisker checks the disk inserted into your target drive. Additionally the information about expected media type and size is provided. To accept the selected drive and target media click "Next".
If the "Erase RW media" checkbox is not checked, but the inserted media is not empty, a popup window will be displayed.
If you click "No", the burining process will be aborted.
There are two erase methods for any rewritable media defined:
Quick-erase: The data is not actually erased from the disk, only the technical information from media header is deleted. Disk is shown as empty, but all sectors still contain the previously recorded data. This method is not suitable for disks with confidential data, but it allows to erase any disks just for 1 or 2 minutes. This method is used by Undisker for erasing.
Full-erase: All sectors will be overwritten with zeros, which means the old data will be completely deleted and can not be restored anymore. However such a process takes the same time as the disk burning itself, and is not used by Undisker by performance reasons.
Only recordable and rewritable disks can be used for CD burning. If the media inserted is not recordable, an error message will be displayed, and Undisker will wait for another media inserted. Burning can be stopped by clicking on "Cancel".
If the target disk is valid and accepted, the write speed can be selected. Corresponding drop-down list will contain only the list of speeds which are supported by your drive. By default the maximum available speed is selected.
After you confirm the operation, the "Burn to CD/DVD" window appears and the writing process starts.
You can cancel the CD/DVD burning process by pressing the Cancel button. Note that when you cancel the writing process, the target media will be damaged. Trying to access such a disk can lead to unpredictable results.
