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' scsibus: 1 target: 0 lun: 0 Using libscg version 'schily-0.8'. Device type : Removable CD-ROM Version : 0 Response Format: 2 Capabilities : Vendor_info : 'TOSHIBA ' Identifikation : 'DVD-ROM SD-R5002' Revision : '1033' Device seems to be: Generic mmc2 DVD-R/DVD-RW. cdrecord: This version of cdrecord does not include DVD-R/DVD-RW support code. cdrecord: If you need DVD-R/DVD-RW support, ask the Author for cdrecord-ProDVD. cdrecord: Free test versions and free keys for personal use are at ftp://ftp.berlios.de/pub/cdrecord/ProDVD/ 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. -- i386 FreeBSD 4.11-STABLE on 2.4 GHz pentium 4 (ASUS P4T533) There are 10 types of people in this world. Ones that understand binary and then, the others.
