RH9 cd burner not there but it is??


I have RH9 and I just noticed that I can't access my CD drive. It is a sony CD-RW drive. When I look at the hardware browser it shows it and it is at dev/scd0. But RH doesn't see the drive. I'm trying to install something off a CD but it says no CD drive present??? I'm a noob so this might be an easy question but I'm lost.

You've probably already tried this but.... did you try mounting it by hand?

mount /dev/cdrom /mnt/cdrom

Ok I have tried the mount cdrom drive and I get ;

[root@localhost root]# mount /dev/cdrom /mnt/cdrom
mount: you must specify the filesystem type
[root@localhost root]#

Did I do this right? Prob not. What should I be typing/trying to do here?

Try
mount /mnt/cdrom

if that doesn't work try
mount /dev/scd0

What are you trying to install?

I am trying to mount a Sony CD-RW drive. I can't use it and RH doesn't see it when I try to install off the cd. When I oper the hardware browser it tells me I have a Sony CD-RW drive at /dev/scd0. I have yet to find a way to look at the drive or use it. Also When I try to use the cd player I get drive error? So part of RH sees the drive part doesn't?

When I boot up and it has all of the OK signs posting I get 1 that says FAILED. I looked at it today and it is for stat cannot mount dev/cdrom or mnt/cdrom. Why would it say that? It pointed to /etc/fstab. This is what my fstab looks like;
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hdb3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

Does this look correct? I am trying to red threw my linux book and I see something about a CD-RW drive needs to be in SCSI emu? Is this the problem? Just lost and trying to figure this out. Please help.

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

these two are unneeded, and probably will cause problems, remove them so there is only one line like that

if the cdrom is already on /dev/scd0 that means that SCSI emulation has already been set up.

also, try the mount command as follows (make sure you have a cd in the drive)

mount /dev/scd0 /mnt/cdrom -t iso9660

Ok here we go.

First off I would like to say thx for all the help people are giving. I removed the 2 extra lines from the fstab file. I also tried ;
[root@localhost root]# mount /dev/scd0 /mnt/cdrom -t iso9660
mount: mount point /mnt/cdrom does not exist
[root@localhost root]#

Is that what you said to do? Also I took another look at when I start up it gives the 1 failed message. It is cannnot stat /dev/cdrom updating ect/fstab. Well thats close to it. Any other ideas or stupid mistakes I'm making? Also is there another file I should be looking at for this or errors about it? Thanks

Create a /mnt/cdrom directory:
mkdir /mnt/cdrom
and then try to mount the cdrw again.
mount /dev/scd0 /mnt/cdrom -t iso9660

/dev/cdrom should be a link to the actual cdrw device so what does the following tell you?

ls -l /dev/cdrom
ls -l /dev/scd0

Also post the relevent lines from the output of the dmesg command pertaining to the cdrw drive so we can see the exact errors.

Ok here we go. I make the /mnt/cdrom dir and tried to mount the drive again.
[root@localhost cdrom]# mount /dev/scd0 /mnt/cdrom -t iso9660
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems
I than ran th Is -l commands and got;
[root@localhost root]# ls -l /dev/scd0
brw-rw---- 1 root disk 11, 0 Jan 30 04:24 /dev/scd0
the -l dv/cdrom gave no such file.

The dmesg output is here; in peices
hdc: SONY CD-RW CRX215E1, ATAPI CD/DVD-ROM drive
SCSI subsystem driver Revision: 1.00
hdc: attached ide-scsi driver.
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: SONY Model: CD-RW CRX215E1 Rev: SS0B
Type: CD-ROM ANSI SCSI revision: 02
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
sr0: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.12

These looked like the peices that had something to do with the cdrw drive. Hope this helps you help me.

Hi
I am getting similar problems with my Ricoh cd writer. When I try to mount it manually I get the same message "Could not mount device.
The reported error was:
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems"

This device is also a DVD reader - that bit works fine. I am also able to burn cds. But Then a music cd is inserted I get the error message - the music cd does start to play but then stops after a minute and a bit. I am unable to browse the music cd and the cd never shows as mounted on the desktop.

I will try removing the cdrom line from fstab and see how I get on.

Ive been having the same prob with my cdrom. But what mythagel posted: mount /dev/scd0 /mnt/cdrom -t iso9660 worked for a dvd but it would not work for a audio cd this is really confusing. What is messed up is that line works for dvd but nothing else. So now if that line works what do I need to change in fstab I have this:
/dev/hdc /mnt/cdrom iso9660 noauto,user,ro 0 0
would I change the /dev/hdc to /dev/scd0..? I guess ill try that ill let yall know what happens

ok well that worked. I now have this in /etc/fstab
/dev/scd0 /mnt/cdrom iso9660 noauto,user,ro 0 0
but I still cant mount regular audio cd's what could possibly be the problem im getting tired of listening to shout cast
oh ya those of you that still have the problem even when you change the fstab file try this: ln -sf /dev/scd0 /dev/cdrom

mcquay18,
Since audio CDs do not have a filesystem they can not be mounted like data cds. Set the players config to point to the cdrom device.

I don't how this works but here is a filesystem to mount audio CDs

Give this a try. Edit /etc/fstab and change to this. I needed to do this since it is a mine is a DVD-Ram Drive. Make sure you have a directory created under /mnt for cdrom ' mnt/cdrom/ '. Then issue ' mount /dev/cdrom /mnt/cdrom ' Another thing to check is to see what /dev/cdrom is pointing to. From your dmesg it looks Ok.

before
/dev/cdrom /mnt/cdrom2 udf,iso9660 noauto,owner,kudzu,ro 0 0
after

/dev/cdrom /mnt/cdrom2 auto noauto,owner,kudzu,rw 0 0


For UDF add UDF to /etc/filesystems.

Hope this helps
Brian
