"format disc: Illegal seek" but still works fine

Hi,

Just want to say I struggled several days because both with my DVD 
writer and CD writer I get the message "format disc: Illegal seek" with 
the commands

"cdrwtool -d /dev/scd0 -q -t 4"

or

"cdrwtool -d /dev/scd1 -m 275616 -t 4".

The fact is that the command exit after 10 minutes, but the writers led 
continue to blink, so I always thought the command was unsuccessful and 
eject the media. But yesterday I went away and come back later. The 
drive was idle and not blinking. I mount the media and tada ! It works 
even with the illegal seek message. I just have to wait that the drive 
stops (40 minutes with my 4X cd-rw).

The funny thing is that "cdrwtool -d /dev/scd0 -i" output is identical, 
whether ejecting the media just after the error or after the 40 minutes.

I know it is not the way it should work, but as I read so many "illegal 
seek" messages searching on google,I think I may interest people that it 
may work even with it.
