HI all,

I have a problem with writing cd's as i am unable to mount [/dev/cdrom1] Mitsumi Cd R/W and k3b also fails to recognize the presence of this drive ...

every time i put in a cd with data and try to mount it ,
it gives me this---->"/dev/cdrom1 not a valid block device.."


Last time i had it working in kernel 2.4.2 ... was also able to write cd's using k3b...
now i have kernel 2.6..


checked the hardware browser as well as [#kudzu -p] it tells me that my

[/dev/cdrom1]Mitsumi Cd r/w is /dev/hdd
[/dev/cdrom] Sony DVD R is /dev/hdc

this is my /etc/fstab entries for my sony dvd/r as well as mitsumi Cd r/w

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,users,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,users,kudzu,ro 0 0


Thanks in Advance............. Guys

Are you getting this error as a standard user, or as root?

i'm getting this as root as well as a standard user..


# ls -l cd*
lrwxrwxrwx 1 root root 8 Feb 12 2004 cdrom -> /dev/hdc
lrwxrwxrwx 1 root root 8 Jul 5 05:49 cdrom1 -> /dev/hdd
lrwxrwxrwx 1 root root 8 May 31 08:06 cdwriter -> /dev/sg0

these r the symbolic links present in /dev... if they could be of any help..

Have you tried editing fstab to mirror the output of kudzu -p so that /dev/hdd /mnt/cdrom1 and /dev/hdc mnt/cdrom to see if that works?

i made the following changes to /etc/fstab

/dev/hdd /mnt/cdrom1 auto defaults 0 0

it didnt work ...

i tried

/dev/cdrom1 /mnt/cdrom1 auto defaults 0 0

No luck still !!!!!!!!!

this is the output of [#kudzu -p]

#kudzu -p

class: CDROM
bus: IDE
detached: 0
device: hdc
driver: ignore
desc: "SONY DVD-ROM DDU1611"
-
class: CDROM
bus: IDE
detached: 0
device: hdd
driver: ignore
desc: "CR-4804TE"

try a `depmod -ae` as root

thanks for all the suggestions..



tried #depmod -ae

it returned no output....


still waiting........

it doesn't return any output. the problem's still there i assume.

yes . the problem still exists...

Are you shure that /dev/cdrom1 is the write path ?
Could it not be /dev/cdroms/cdrom1 ?
Can you mount you cdroms ? mount /dev/cdrom1 /mnt/cdrom (does it work)
If not do mount /dev/cdroms/cdrom1 /mnt/cdrom work ?

I think the problem is in you fstab.

The other thing is that you may have miss spelled in fstab.
Try:
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,users,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,users,ro 0 0

Hope it will lead to something.

Eureka!!!!!!!! i did it......

i changed my /etc/fstab to the following

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,users,owner,kudzu,ro 0 0

The real problem was with my ****grub.conf*****

My original grub.conf enty read like this

kernel /vmlinuz-2.6.6-1.435 ro root=LABEL=/ hdd=ide-scsi

I had to change it to...

kernel /vmlinuz-2.6.6-1.435 ro root=LABEL=/ hdd=ide-cd


The [ ide-cd ] did the trick !!

This is the problem if one made a transition from kernel 2.4 to kernel 2.6 on my Redhat 9 [2.6.6 kernel] .

Anyway.. once again thanks all of u guys out there for your suggestions....
