Augmenting images with error correction data |
Walkthrough
dvdisaster is specialized in working with error correction data and reading of defective media. Creating ISO or UDF images and writing them to a medium is a totally different business, and also bears high complexity. We do not want to re-invent medium writing in dvdisaster. Instead we continue using the CD/DVD/BD writing software which you have got when purchasing your drive.
|  | First create an ISO image using your CD/DVD/BD writing software. Select the files you want to write to medium, but do not start the writing process yet. Instead, create an ISO image on your hard disk. Click on the image to the left to see a detailed walk-thorugh.
|  | When you have prepared the image switch over to dvdisaster. Make sure that it has been configured as described in the basic settings.
|  | Select the directory and file name of the ISO image which you have just created.
|  | Augment the image with error correction data by clicking on the "Create" button.
Please wait while the error correction data is created. This may take a while depending on the image size and the available free space on the medium. Processing a DVD image with about 20-30% free space should take about 5-10 minutes on recent hardware.
Screen shot: Creating error correction data.
|  | Please note: dvdisaster does not create a new image, but will rather augment the existing one. Look at the image in the file manager before and after processing it with dvdisaster and note how its size increases.
|  | Write the augmented ISO image on the medium. Select the augmented image in your writing software and start the writing process. Click on the screen shot to the left for a detailed example.
|  | Finished! You have now created a CD which is protected by error correction code.
Related information Check whether the writing process has affected the error correction data. It is recommended to perform this test once every time you change to a new version (or vendor) of your media writing software to make sure that it interoperates well with dvdisaster.
