[Linux] Check if your CD was successfully burned

Intro

Under Linux there is a small utility that allows you directly to verify file integrity by comparison. It is call md5sum that calculates the md5 sum of a file.

• You will often notice that for some sites the md5sum of a file available with the download linl.
• Once you've downloaded your file, just type in a shell:

  • md5sum path_of_file

• And you will get the md5sum of the file and from there you can compare with that offered by the site. It ensures the integrity of a download.
• This concept can be used in the same way to check if your CD has been successfully burned.
• Simply by comparing the .iso file to the burned CD.
  • Note that under Linux you have direct access your devices through the /dev directory
• In this directory, the CDs are often represented by their ide path:
  • /dev/hdX(where X is the letter of the location of the cdrom on the ide layer)
• The master of the first layer is /dev/hda
• The slave of this layer is /dev/hdb
• The master of the second layer is /dev/hdc etc. .....

Notes

• But you can also have shortcuts with /dev/cdrom0 /dev/cdrom1 ....

Implementation

Consider that your burner is the master of the second IDE layer:/dev/hdc

• After burning your iso image, you just have to do a sum on your iso file:

  • md5sum path_of_iso

• And compared with the sum of your burned CD:

  • md5sum /dev/hdc

• If the md5sum is the same for both, then your burn is successful.
