It seems that you are using the wrong devices.....

You started with dev=1,0,0, why did you try to use a different device later on?

What if the correct UNIX device name for SCSI dev=1,0,0 on your machine?

I recommend you to start with a 

	cdrecord -scanbus

If there is only on CD-ROM type device on your machine, cdrecord will use the 
right one without a need to specify dev= - read the man pages....

If you like to access the block device (e.g. four mounting), you need to know 
the UNIX device name, I hope that you know the right names for your machine.

Given the fact that you did not report about errors from the first write 
process, I assume that you used the right device. Given the fact that you could 
not mount the device, I assume that you used the wrong UNIX device name.
