If you are new to Ubuntu you will notice that Brasero burns discs quite slowly compared to the windows counterparts such as Ashampoo Burning Studio or Nero. Its not that Brasero is slower than the other ones. Its just that, by default it is configured to do some tasks which other burners don’t usually perform by default. What I’m talking about is Image Checksum. Image checksum is created to verify that all the data that you wanted to be burned, burned properly onto the disc. A checksum is a big number formed by computing some arithmetic operations on the data present. When the same arithmetic operations(predifined to generate unique checksums called md5) are performed on the data that you wanted to be written and the data that is present in the disc after it has been written it should produce the same checksum. That would prove that the data has been written properly.
But more often than not, this laborious process is not needed. Because our DVD writers are mostly good enough to write everything properly. So disabling it would be ideal as it would save a LOT of time. It would cut off about 60% of the time.
How do you do it
All you have to do is open Brasero Disc Burner through what ever means is comfortable to you. In the newer versions of ubuntu, the application can be opened by hitting the windows button (what an irony) and typing in brasero. While on older Ubuntus, you have to head to Application>Sound & Video > Brasero Disc Burner.
Once that is opened. Go to Edit > Plugins. Uncheck the File Checksum and the Image Checksum boxes. That would do the trick. We do not need both in almost all cases.
The File checksum computes the checksum for the files that you give initially to write. The Image Checksum computes the checksum for the Image that has been burnt to the Disc, or in other words, it computes the checksum for the data in your disc. Both these checksums are computed and compared with each other in a default process.
