CD/DVD Setup Problems

**Bubo** · 06-04-2005

Could you expand on that a little please. I am not quite sure I follow.

What do you mean by "read-only disk", the media used, in which case it was definately a CD-RW, or the block device itself, /dev/hdc.

Thanks

Linux doesn't know it's a writable disk, and linux itself is unable to write anyway. As far as the basic linux mounting system is concerned, it's a read-only disk and drive. You have to use other programs (which I have no experience with, and in fact I don't even know what they're called) to write to a CD or DVD.

Right, I have done a bit of reading and would like to bottom this thing out once and for all.

When I run

Code:

cdrecord -scanbus

I get this error

Code:

root@ccu-linux&#58;~# cdrecord -scanbus
Cdrecord-Clone 2.01 &#40;i686-pc-linux-gnu&#41; Copyright &#40;C&#41; 1995-2004 Jörg Schilling
cdrecord&#58; No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord&#58; For possible targets try 'cdrecord -scanbus'.
cdrecord&#58; For possible transport specifiers try 'cdrecord dev=help'.

From what I have read I need to add

Code:

insmod ide-scsi

to my rc.local.

At the moment it looks like this

Code:

#!/bin/sh
#
# /etc/rc.d/rc.local&#58;  Local system initialization script.
#
# Put any local setup commands in here&#58;

Would this do the trick

Code:

#!/bin/sh
#
# /etc/rc.d/rc.local&#58;  Local system initialization script.
#
# Put any local setup commands in here&#58;
insmod ide-scsi

I don't want to do anything that will mess up the system boot, so I thought I would ask before I reboot.

Any offers ?

Finally resolved this issue - thankfully.

It turned out to be user error, ie me getting it wrong.

It was as simple as adding

Code:

append="hdc=ide-scsi"

to lilo.conf, not

Code:

append="hdc=ide=scsi"

as I had it.

It just goes to show how careful you need to be with the syntax when editing files. One character can make a lot of difference as I found out.

Now, what else can I break before lunch..................

Thanks to all those that contributed.
