burncd data (error)

[$mage]

Hi,
Im trying to burn a an iso image to a cdr. I used mkisofs with boot.flp to
create my 4.8-boot.iso image. I am doing this cuz my floppy drive died.
When I do:

burncd -f /dev/acd0c -s max data 4.8-boot.iso fixate

I get the following:

next writeable LBA 557
writing from file 4.8-boot.iso size 2976 KB
acd0: WRITE_BIG - ILLEGAL REQUEST asc=0x64 ascq=0x00 error=0x04
only wrote -1 of 32768 bytes err=5
fixating CD, please wait..

acd0: CLOSE_TRACKING/SESSION - ILLEGAL REQUEST asc=0x72 ascq=0x04 error=0x04
burncd: icotl(CDRIOCFIXATE): Input/output error

Any insight on this issue?
Thanks. -smage
