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.<p>

<b>Detailed example: Creating an ISO image on hard disk</b>.
|
|
Since there are many different media writing programs available we
|
|
are demonstrating the required steps by using
|
|
the popular GNU/Linux software <i>K3b</i> as an example.
|
|
If you are using a different software you should be able to figure
|
|
out the required actions from the descriptions below.

First open your media writing application. Many programs expect you to

start a new project. Within the project you will then make
|
|
the selections for the new medium. <p>
|

Using K3b: <i>Begin a new project by clicking into the highlighted field

Typically there is a file selection dialog from which you can select files

Using K3b: <i>Choose the required files in the upper half of the window.

In the example the files <i>backup.tar.gz</i>,

<i>win.zip</i> and <i>work.tar.gz</i> have been selected for writing onto CD.

<b>Important:</b> Do not completely fill the medium. Make sure to keep

at least 20% of the medium space for the error correction data.<p>

Using K3b: <i> The currently used medium space is shown in the green bar
