I did see
enough logs from cdrecord that verify the fact that Linux does not allow
cdrecord to work correctly under all conditions. This is because Linux does
not allow all the SCSI commands cdrecord needs for it's work unless
cdrecord runs with root privileges.

      

Can you please tell me what commands are affected by the root problem?
    

All vendor unique commands, such as for Yamaha/Plextor specific functions.

  

I believe this is true, but just writing a disk is hardly vendor specific.

All commands for old (pre-MMC) writers.

  

That is clearly going to be true.

Some MMC commands needed for DVD writing, but here I do not remember the
commands.
  

On this, since other software writes disks, I would classify these commands as "desirable" rather than "required." Feel free to list commands you feel are necessary to the basic functionality if you can identify any.

Note: I completely agree that some commands are blocked which would be desirable, but the general case, "put data on a disk" can be done without root if a standard MMC device is being used.
