|
|
|
|
The image file contains the data from all medium sectors, including the information
|
|
whether a sector was readable. dvdisaster works on image files because they are
|
|
stored on hard disk which makes certain random access patterns much faster.
|
|
Applying this kind of random access to CD/DVD/BD drives would slow them down
|
|
significantly and eventually wear them out (the image files are created using
|
|
sequential access which unlike random access is handled efficiently by the drives).
|
|
The default file suffix for images is ".iso".<p>
|
|
|

|

<td class="valignt">
|
|
There are two ways of choosing the image file:
|
|
<ul>
|
|
<li>using a <a href="howtosa2_expand=2.html#filechooser">file chooser dialog</a> (button marked green), or</li>
|
|
<li>by directly entering the file location (text entry field marked blue).</li>
|
|
</ul><p>
|
|
The direct entry is helpful when you are processing several files
|
|
in the same directory. In that case simply change the file name in the text field.

<b>Notes for using the file chooser under Windows and Mac OS X</b><p>
|
|
|
|
dvdisaster uses the <a href="http://www.gtk.org">GTK+</a> user interface toolkit
|
|
which makes sure that it runs on many different operating systems. Since the
|
|
GTK+ file chooser behaves differently from its Windows and Mac OS X counterparts (which we
|
|
can't use), a small introduction is included further down this page.
|
|
Please note that creating the Windows or Mac OS X version would have required
|
|
a huge effort without GTK+ - we would probably just have concentrated
|
|
on doing the GNU/Linux version instead ;-)<p>
|
|

|
<b>Choosing existing files.</b>
|
|
The areas marked <span class="green">green</span> are used for choosing existing files.
|
|
Directories are picked and navigated in the left half of the dialog; the files
|
|
contained are shown and selectable in the right half.<p>
|
|
|
|
<b>Choosing a name and location for new files.</b>
|
|
First choose a directory for the new file using the
|
|
<span class="green">green</span> area in the left half of the dialog.
|
|
Then enter the name for the new file in the
|
|
text field marked <span class="blue">blue</span>.
|
|
To double check that you are creating the file in the right place please review
|
|
the "Selection:" caption of the <span class="blue">blue</span> field; it contains the
|
|
drive letter and directory path under which the new file will be created.<p>
|
|
|
|
<b>Switching between partitions ("drive letters").</b>
|
|
|
|
The available partitions are listed in
|
|
the <span class="yellow">yellow</span> marked area. If the currently selected drive
|
|
contains lots of subdirectories you might have to scroll down to see the
|
|
drive letters.<p>
|
|
|
|
<b>Going back to the parent directory.</b>
|
|
Click on the two dots (..) marked <span class="red">red</span>
|
|
to go back one directory level. All directories leading up to the current one
|
|
are contained in the drop down menu centered at the top of the dialog
|
|
(also marked <span class="red">red</span>).
|
|
Note that this drop down menu is <i>not</i> used for switching drive letters;
|
|
please use the <span class="yellow">yellow</span> part of the selection for that.
