### Using dvdisaster the right way

Let's demonstrate how Jane uses dvdisaster.

10. Feb. 2004 |  |  | Jane creates a new CD with important data.
|  |  | To protect the CD from data loss she creates error correction data with dvdisaster. She keeps both kinds of data for later usage.

14. May 2005 |  |  | Jane knows that during daily use not all data of her CD might be accessed. So after a year has passed she scans the CD for read errors to make sure that it has not developed any defects in seldom used data regions. However after one year the CD is still perfectly readable.

19. Aug 2007 |  |  | Two more years have passed and Jane notices that some data on the CD is no longer readable. A scan for read errors confirms that the CD has become defective due to aging.
read |  |  |
|  |  | Jane uses dvdisaster to read as much sectors as possible from the defective CD into an ISO image.
reconstruct |  |
|  |  | By using the error correction data Jane recovers the missing parts in the ISO image.
Write new CD |  |  |
|  |  | Jane writes a new CD from the recovered ISO image. She keeps the error correction data for the new CD as it may also become defective in the future.
