On Sun, Dec 10, 2000 at 05:00:55PM -0500 or so it is rumoured hereabouts,

Have you checked your /etc/cdrecord.conf?  This contains values which are
used by default if not specified on the cdrecord commandline.  For
instance, my setup gives;

[root at Valkerie /root]# cdrecord -scanbus
Cdrecord 1.9 (i686-pc-linux-gnu) Copyright (C) 1995-2000 Jörg Schilling
Linux sg driver version: 2.1.38
Using libscg version 'schily-0.1'
scsibus0:
cdrecord: Warning: controller returns wrong size for CD capabilities page.
	0,0,0	  0) 'LITEON  ' 'CD-ROM LTN382   ' 'UL24' Removable CD-ROM
	0,1,0	  1) 'PHILIPS ' 'CDD3610 CD-R/RW ' '3.01' Removable CD-ROM
	0,2,0	  2) *
	0,3,0	  3) *
	0,4,0	  4) *
	0,5,0	  5) *
	0,6,0	  6) *
	0,7,0	  7) *

Note the CD-RW is on scsi device 0,1,0 and is a 2x Phillips.  My
/etc/cdrecord.conf looks like;


#ident @(#)cdrecord.dfl	1.1 98/12/06 Copyr 1998 J. Schilling
#
# This file is /etc/cdrecord.conf
# It contains defaults that are used if no command line option
# or environment is present.
# 
# The default device, if not specified elswhere
#
CDR_DEVICE=phillips

# 
# The default speed, if not specified elswhere
#
CDR_SPEED=2

# 
# The default FIFO size if, not specified elswhere
#
CDR_FIFOSIZE=4m

#
# The following definitions allow abstract device names.
# They are used if the device name does not contain the
# the characters ',', ':', '/' and '@'
#
# drive name	device	speed	fifosize
#
#teac=		1,3,0	-1	-1
#panasonic=	1,4,0	-1	-1
#yamaha=	1,5,0	-1	-1
#cdrom=		0,6,0	2	1m
phillips=	0,1,0	2	-1

Always useful to try this stuff from commandline first when
troubleshooting!
