If your shell is bash,  `man bash' (look for REDIRECTION)

For bash, to redirect both std error and std output use  
your_command >errorfile 2>&1

or even simpler,

your_command &>errorfile

I am just guessing:

You probably have a blank disk with no filesystem on it. If you are
trying to write something on to the disk, use a cd writer program 
(eg., cdrecord, xcdroast, ..) The writer programs will  directly access
/dev/scd0 using scsi commands. Do take a look at CD-Writing-HOWTO.

Happy burning !
