Whoops!  Sorry, that was my bad.  I typed this out from memory:

But the later ones I copied directly from the screen.  I am not really switching devices; I just got the machines confused when I typed the first command.

Yes, I use dev=2,0,0 for the initial cdrecord.  I got this number from cdrecord -scanbus.  Using this device does not generate any errors.

> Given the fact that you could not mount the device, I assume that you used the wrong UNIX device name.

I use /dev/sr0 to mount the device.  I cannot mount the drive, using /dev/sr0 OR /dev/dvd, after the first write without manually reloading the tray. After I reload the tray, /dev/sr0 mounts just fine.  I cannot perform the second write at all, as I said.  From reading the man page, I think I am supposed to use the UNIX device name with the -M in mkisofs, but mkisofs does not like /dev/sr0.  It did attempt to write when I used /dev/dvd, which is a link to /dev/sr1, but I don't know enough about Linux device names to know why.  As I said in my first email, the attempt to write was unsuccessful.

Yes, I read that in the man pages, but there is a second CD-ROM device that confuses things.  The KVM that this machine is on attaches a "bonus" device via USB, which for some reason shows up as a CD drive at 0,0,0.  This is why I specify the dev.

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.
