I went to sdd.toshiba.com and got the latest firmware. Didn't help though.
Here's some output from cdrecord showing versions:
Cdrecord-Clone 2.01 (i386-unknown-freebsd4.11) Copyright (C) 1995-2004 Jörg
Schilling
scsidev: '1,0,0'

Using generic SCSI-3/mmc CD-R/CD-RW driver (mmc_cdr).
Driver flags : MMC-3 SWABAUDIO BURNFREE
Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R96R
I don't know if I'm doing something wrong with mkisofs or cdrecord. I'm
following the example at:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html
In an attempt to eliminate buffer underruns as being a problem, I use:
nice -18 (or -35 even) cdrecord -driveropts=burnfree cd1.iso (note that
in /usr/local/etc/cdrecord I've included a def for toshiba as 1,0,0 and made
it the default recorder).
I'm only burning <2 MB, or < 4 MB (I eliminate all but one directory to get <
2 MB). Ive mostly been using TAO, but I've tried DAO and PACKET.
