catting cd img onto hd

towlie · 04-23-2005, 04:05 PM

Well, maybe this is a dumb question, but I've searched
and just don't know where to start.

Using an x86 box with cd writers on primary ide slave and
on secondary ide master.

EDIT: Forgot to say I'm using scsi emulation,
which is why I tried sr0 and sr1.

Here's my failed attempt to get an image:

Code:

[root: music] ls -l /dev/hdb /dev/hdc /dev/sr0 /dev/sr1 /dev/topcd /dev/botcd
lrwxrwxrwx  1 root root       3 2005-04-23 14:50 /dev/botcd -> sr0
brw-rw----  1 root disk   3, 64 2002-06-09 14:27 /dev/hdb
brw-rw----  1 root disk  22,  0 2002-06-09 14:27 /dev/hdc
brw-rw----  1 root cdrom 11,  0 1999-04-12 23:24 /dev/sr0
brw-rw----  1 root cdrom 11,  1 1999-04-12 23:24 /dev/sr1
lrwxrwxrwx  1 root root       3 2005-04-23 14:50 /dev/topcd -> sr1
[root: music] cat /dev/topcd > test.raw
cat: /dev/topcd: Input/output error
[root: music] cat /dev/hdc > test.raw
cat: /dev/hdc: Input/output error
[root: music] cat /dev/sr1 > test.raw
cat: /dev/sr1: Input/output error

dd doesn't work either.

I've got no idea where to start, so could someone point
me in the right direction?

ON A MUCH MORE POSITIVE NOTE:
Just got my sound card working on slackware. That was the only
reason I still had win2k on my machine, so now I'll be removing
the last trace of M$ forever.

Thanks to everyone here at lq for all your help.

You want an image of a CD ?

Code:

mount /mnt/cdrom
mkisofs -o cd.iso /mnt/cdrom

d'oh, I should have told you, these are audio cds I'm
trying to get images of, so they cant be mounted (right?).

Trying something else right now, I'll let you know if it works.

thanx

So, try cdrdao

Code:

cdrdao scanbus
cdrdao read-cd --datafile audiocd.bin --device <X,X,X>

keefaz, thanks for your help.

Tried cdrdao, and ended up with a cd that had all
the audio but just on a single, 68-minute track.
Maybe i did an option wrong or something.

This finally worked:

Code:

cdparanoia -v -d /dev/whatever -B 1-15

cdrecord -dev=x,y,z -speed=32 -nopad -audio track01.cdda.wav ...... track15.cdda.wav

Well, I'm glad that worked, but does anyone know why catting
wouldn't work there. Isn't that the standard way to get
a disk image?

Take a look at cdrecord's man page specially the EXAMPLES section which has some examples (obviously... :P ) on how to copy a cd to another cd and how to rip and burn several tracks at once.

keefaz · 04-24-2005, 04:36 PM

For the cdrdao tool I forgot the TOC file, this file provides infos about the cd tracks
(like nero's cue files)

Code:

cdrdao read-cd --datafile audiocd.bin --device <X,X,X> cd.toc

Thanks everyone, I've looked at man cdrecord many times, but
now that you said that, i saw this down in the ex section.

These 2 scripts worked for me:

acdrip:

PHP Code:



#!/usr/bin/php 
<?php 
 
$usage= "acdrip <top|bot>\n"; 
$dev= ''; 
$comm= ''; 
 
 
if(count($argv) != 2) die($usage); 
 
if($argv[1] == 'top') $dev= '-D0,1,0'; 
else if($argv[1] == 'bot') $dev= '-D0,0,0'; 
else die($usage); 
 
$comm= "cdda2wav -vall $dev -B -Owav"; 
 
system($comm); 
print "\n"; 
 
?>

acdrec:

PHP Code:



#!/usr/bin/php 
<?php 
 
$usage= "acdrec <top|bot>\n"; 
$dev= ''; 
$comm= ''; 
 
 
if(count($argv) != 2) die($usage); 
 
if($argv[1] == 'top') $dev= '-dev=0,1,0'; 
else if($argv[1] == 'bot') $dev= '-dev=0,0,0'; 
else die($usage); 
 
$comm= "cdrecord -v $dev -dao *.wav"; 
 
system($comm); 
print "\n"; 
 
?>

If you have multiple drives, that lets you rip from/burn to your
drive of choice, it'll fill the cwd with .wav files. Just replace the
dev options with the freaky parameters that work on your system.

Hey it looks cool in php

gbonvehi · 04-24-2005, 05:33 PM

Oh by the way, regarding to why cat doesn't work, I guess it's because it finds EOF flag (End Of File) lines long before reaching the end of the CD, it should work if the CD doesn't contain it.
You could try using dd instead that will do raw reading or writing (same as cat but in a binary way).

towlie · 04-24-2005, 05:56 PM

keefaz and gbonvehi, thanks for your replies.

yeah, i tried dd, but it wouldn't work (although I could've
been doing something wrong there too

)

But here's why I think it's lower than that:
I even tried writing a dummy c program using
fopen("/dev/xxx", "r") just to see if I could get
a lock, but no success.

Dunno, just feels like one of those times when
you just know if you knew the right dev name,
everything would work perfectly.

If figure out how to get a true image, I'll post it,
but I'll probably just use this for a while as it
works smoothly for me.
