Manually Testing CD Media

To manually test CDs, you will need to use the dd command line utility.

First insert the CD to be tested into your CD/DVD drive. Do NOT mount the drive. If you have a file manager that automatically mounts this device when you insert a disc, you will need to disable this feature.

Now enter the command:

dd if=/dev/cdrom bs=2k | md5sum

This will return a 32 character string which is the checksum of the CD image. You can find the correct value in the MD5SUM document where you downloaded the CD image from in a file called MD5SUMS.

Remove the CD and repeat for the other CDs.

If you have problems with these instructions, please submit a bug against the anaconda component at Bugzilla. displayFooter('$Date: 2005/11/29 17:30:35 $'); ?>
