UPDATE: Upon plugging the firewire hard drive I get this from the kernel:

It seams like udev does not recreate /dev/sr0 and I have create it by hand to use the drive again without rebooting. My test results show that out of 7 plugging and unplugging a firewire hard drive to be sucessful but with the CDRW I can only get one use out of it before I have to step in. -adam
