[NTLUG:Discuss] Multiple CD-R/W's and Fedora Core 2

[David Simmons]

Guys,

Thought this might help others that have been 'bitten' by the way that
Fedora Core 2 handles CD-R/W's.  I'm sure it's an improved/more-mature
way of doing things, it just broke my long-term scripts - here's a way
to 'fix' them.

My machine has two IDE CD-R/W's that I use to create company Promo-CD's
with.  I have two scripts, called top.sh and bottom.sh (corresponding to
the drive locations).  These drives are on their own ATA card so-as not
to interfere with IDE hard-drives (thanks Bryan!).  Here are my
old/original scripts:

[root at localhost root]# cat top.sh.BEFORE-FC2
cdrecord -v -speed=24 -dev=0,0,0 -data -driveropts=burnfree -eject
-fs=24m
/home/dsimmons/CD-Dave2003Nov.iso
[root at localhost root]# cat bottom.sh.BEFORE-FC2
cdrecord -v -speed=24 -dev=0,1,0 -data -driveropts=burnfree -eject
-fs=24m
/home/dsimmons/CD-Dave2003Nov-2.iso


When they are run on Fedora Core 2, the script complains about not being
able to find/talk to the device.  So, I did as suggested and ran
'cdrecord -scanbus':


[root at localhost root]# cdrecord -scanbus

It see's my two drives...but has 'renumbered' them from the
original....and by reading the MAN CDRECORD, I need to define the TYPE
of drive/transport I want to use...ie. needed to include ATAPI: infront
of my device names...BUT **GOTCHA** don't believe the scsibus
designations.  You'll need to start at 0 and not 1 (ie. it showed by
devices as 1,0,0 and 2,0,0 - but in reality they needed to be 0,0,0 and
1,0,0)....here's what I mean, by examining my corrected/updated scripts
that work:


[root at localhost root]# cat top.sh
cdrecord -v -speed=24 -dev=ATAPI:0,0,0 -data -driveropts=burnfree -eject
-fs=24m /home/dsimmons/CD-Dave2003Nov.iso
[root at localhost root]# cat bottom.sh
cdrecord -v -speed=24 -dev=ATAPI:1,0,0 -data -driveropts=burnfree -eject
-fs=24m /home/dsimmons/CD-Dave2003Nov-2.iso


Hope this helps - I'm by no means an expert...I was just lucky enough to
figure it out.
