     Merely a report from the world where we may still burn a CDROM or
     some other hard spinning media like a DVD.

     Yesterday I had no other option than to burn a DVD-RW in order to
     get FreeBSD installed on some slightly oddball hardware. I did use
     a Devuan Linux x86_64 machine running with Linux kernel 5.19.2 and
     whatever the latest glibc is from the Debian/Devuan folks. Looks
     to be 2.34 with patches.

     The cdrecord works flawlessly with a SATA attached DVD burner and
     then I used readcd to confirm that the data on the DVD-RW media was
     precisely the same as the source. The order of operations to get
     that done :

     1 - determine the devices that are available with :

             cdrecord -v -scanbus

     2 - use the device number determined in (1) to blank the
         media :

             cdrecord -v -dev=x,x,x blank=all

     3 - check the sha256 hash of the FreeBSD install iso image :

             mdigest -a sha256 freebsd_13.1_i686.iso

     4 - after verify that the sha256 hash is correct from the
         FreeBSD folks I then do the burn to DVD-RW :

             cdrecord -v -dev=x,x,x -fs=32m driveropts=burnfree -sao ...

     5 - once that was complete I then read back the data that
         was burned :

             readcd -v -dev=x,x,x meshpoints=32 f=test.iso

     6 - verify the sha256 hash of the data read from media :

             mdigest -a sha256 test.iso


     The process is a bit manual of course but also works like a charm.
