| Creating error correction files |
 |
| from a medium |
Please make sure that dvdisaster has been configured as described in the
basic settings section as some selections might
create sub optimal error correction data.
The next steps depend on the source for the error correction data. Select between
these two ways:
 |
|
Insert the medium you want to read into a drive
which is directly connected to your computer.
You can not use network drives, software drives and drives inside virtual machines.
|
|
|
Close any windows which may be opened by your operating system
for viewing or performing the medium contents.
Wait until the drive has recognized the medium and the medium has spun down.
|
|
|
Select the drive containing the medium
in dvdisasters drop down menu.
|
|
|
Select a directory and file name
for storing the ISO image. |
|
|
Create the ISO image from the medium by clicking
the "Read" button. |
| |
Watch the reading progress.
Wait until the medium has been completely read. If the medium turns out
to contain defective sectors it will not be possible to create error correction data.
|
|
|
Select a directory and name
for storing the error correction file. |
|
|
Create the error correction file
by clicking the "Create" button. |
| |
Wait until the creation process finishes.
This may take a while depending on the image size and the selected redundancy.
For example creating an error correction file using the "normal" redundancy setting
will take about 5 minutes for a 4GB sized DVD image and using standard hardware.
|
 |
|
Wrapping up. You can delete the image file now. However you
must keep the error correction file and, even more important, protect it from being
damaged. Refer to the next page for some suggestions about
error correction file archival.
