cdrecord error

[Jason Majors <jason@kwiqsilver.org>]

I'm trying to use cdrecord with a new ide cdrw.
I went through the ide-scsi howto I found and I now get the following lines
in dmesg, and I can mount the drive as /dev/sr0.

--dmesg
SCSI subsystem driver Revision: 1.00
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
  Vendor: OPTORITE  Model: CD-RW CW4802      Rev: 150E
  Type:   CD-ROM                             ANSI SCSI revision: 02
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
--dmesg

But when I try to run "cdrecord -scanbus" as root, I get:
cdrecord: Read-only file system. Cannot open '/dev/pg0'. Cannot open SCSI
driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are
root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

On my other box with the dead scsi cd burner, I notice it opens /dev/sg0 and
in the dev=help option, I noticed that pg is related to parallel port
burners.
Is cdrecord trying to read a parallel port drive? If so how can I get it to
change?

Thanks.
