cd and cd/dvd problem


I can not write to either cd-rw or cd/dvd-rw.
Tried several cd's recorded as far back as 2001.
Installed different cd-rw and cd/dvd-rw with no luck.
I can not mount as root.
[root@localhost dvd]# mount /mnt/dvd
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems
[root@localhost dvd]# mount /mnt/cd
mount: block device /dev/hdd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
or too many mounted file systems

When I try to write to a cd, k3b acts as if it did.
The cd physicaly looks like there is something on it.
(different color close to the center)

Here is /etc/fstab:
/dev/hdc /mnt/dvd iso9660 user,noauto,exec,default 0 0
/dev/hdd /mnt/cd iso9660 default,noauto,user,exec 0 0

Any ideas?

Does your kernel have support for iso9660 filesystems built in? Cat /proc/filesystems to check. Let me know how it goes.

Make sure you are not trying to mount audio cd's.

Check in k3b and make sure you are not creating multisession cd's. The cd needs to be finalized before you can mount and read from it.

Can you play audio cd's?
Can you read regular store bought data cd's?

What distro, kernel?

Is this a homegrown kernel or one from your distro?

<edit> Can you read the cd on another computer/os?

>>They are data cd's.

>>Trying to mount a data cd I made.
>>[root@localhost don]# mount /mnt/dvd
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems

>> Trying to mount a store bought data cd.
>>[root@localhost don]# mount /mnt/dvd

or too many mounted file systems

Check in k3b and make sure you are not creating multisession cd's. The cd needs to be finalized before you can mount and read from it.
>> I always make my data cd's multisession.
>> After it writes the data, k3b finalizes what it did write.

Can you play audio cd's?
>> Yes, I'm listening to Kenny G now.

Can you read regular store bought data cd's?
>> No, see above atemp to mount a store bought cd.

What distro, kernel?
MDK 10.1 kernel 2.6.8.10

Is this a homegrown kernel or one from your distro?
>> No, the kernel is from MDK 10.1

<edit> Can you read the cd on another computer/os?
>>I tried in my laptop but have the same problems as above.
>> Now, I used the same MDK 10.1 cd's to install MDK on it.
>> This is the first time I've tried using a cd in the laptop since I installed MDK 10.1.

I'm going to take several cd's to a friend later.
I'll post my findings.
