cdrecord -scanbus sez: "controller returns wrong size for capapabilities page
I am still trying to find out how to use mkisofs and cdrecord and the front-end to these programs, gcombust. I have finally found out how to get both my CDROM and CDRW to look like SCSI devices to linux (append="hdc-scsi hdd-scsi" as last line in the stanza representing the version of linux you wish to use).
However, when I type "cdrecord -scanbus", I get:


Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling
Linux sg driver version: 3.1.17
Using libscg version 'schily-0.5'
cdrecord: Warning: controller returns wrong size for CD capabilities page.
        0,0,0    0) 'E-IDE  ' 'CD-ROM 56X      ' '13  ' Removable CD-ROM
        0,1,0    1) 'IDE-CD  ' 'R/RW 4x4x24    ' '1.04' Removable CD-ROM
        0,2,0    2) *

Please note the warning: Is this a problem? Is it necessary to change something in a config fil file? Perhaps /etc/cdrecord.conf?
Here is my cdrecord.conf:

#ident @(#)cdrecord.dfl 1.2 00/04/16 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

# The default speed, if not specified elswhere

# The default FIFO size if, not specified elswhere

# 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 driveropts
# teac= 1,3,0 -1 -1 ""
# panasonic= 1,4,0 -1 -1 ""
# plextor= 1,4,0 12 -1 ""
# sanyo= 1,4,0 12 -1 burnproof
# yamaha= 1,5,0 -1 -1 ""
# cdrom= 0,6,0 2 1m ""[

Do I need to change CDR_FIFOSIZE=4m? If so, to what? Or is there something else? 10-04-2001 12:42 AM

Got tired of waiting for answer
I read the documentation again and just dove in.
I had to change lilo.conf append line. Here it is:

append="hdc=ide-scsi hdd=ide-scsi"
It is necessary to creat an image of whatever you wish to copy.
You do this by:[list=1][*] making a directory in which you place the stuff you want to put on your CD. If you have a bunch of stuff already in a directory, use that.[*]Next step is to make an image using "mkisofs".[*]After that, you burn your CD using "cdrecord"[/list=1]

I have yet to find a way to copy a purchased CD containing music.

You must be able to extract the audio first to copy music cd. else you are just copying the TOC I guess 10-05-2001 10:22 PM

Tell me more[list=1][*]Where do I start/[*]Where to I find the software?[*]Anything else you can think of.[/list=1]

maybe try this out, these two links explain the process of extracting audio to wave or au or whatever files to disk using cdafs , and the second one explains building audio cd from these files, tracks etc.

Accessing Audio CD as filesystem from Linux


stuff on writing audio cd

There is a lot of stuff out there, if you don't like these, search for audio cd howto at google for more help. You should get over 24,000 results. 10-08-2001 10:09 AM

Thanks for the input. I have been all over the place, including, but haven't found quite what I am looking for. Maybe it doesn't exist? All I want to be able to do is to plop a music disk in my CD-R and have my CD-RW copy it verbatum. I am going to go look at the two URLs you suggest, then will post more.

Okay, I am back. I downloaded the file you refer to in the first suggested URL. I am on my windows box right now and will play with the software later.

As for the HowTo you recommend. I have read this several times in the past several weeks and have come away slightly overwhelmed by the amount of jockying around that is necessary compared to what is required to do the same thing in windows. In Windows, I slap a CD into the CD-R and a CD-Readable into my CD-RW, click a couple buttons and away we go. The stuff I have read about linux tells me that linux is more dependable and breaks down less often. Only problem is, I cannot just copy a disk verbatum, but have to create a bunch of images...doesn't make sense yet.

I will try the software you suggest, then see where we go from here.
