Please guys anyone will burn cd's take care of the following notes:

• BEFORE you start burning, make sure that your source CD is running fine by checking its md5sum as said down on this page.
• Don't burn on a speed higher than 24X, u can make it less than that depending on your hardware.
• While you are burning, check the cd's that you burnt by checking its md5sum, If you are short in time, at least check 25% or 20% of it. If you found errors then you'll have to check them all and mark the bad ones. If the damaged CD's are more than 5% of what you burnt then stop immediately and get the rest of the blanks with you tomorrow.

How to check the md5sum:

Checking a cd's md5sum:

1. put the cd in the cdrom and open a terminal.
2. type the following command:

md5sum /dev/cdrom

1. the output of this command should be exactly:

ace23d1579431ebe767ab8eac25cdbc4   /dev/cdrom

1. If it's different then stop burning immediatly.

Checking a .iso file:

Same way, just change the command to be:

md5sum /path/to/the/file.iso

The output should be the same string as above (of course /dev/cdrom will be changes to where your file is).
