dmesg | egrep "CD|DVD"
What do you mean by "broken"? The files are missing? ├В┬┐They are all sym links to a non existeng file?

Check the physical connections. Make sure the device has power and no conflict with other ide devices.
rm or rmsf the devices and restart the system.

Re: dvd/cd to work on rhel 5
dmesg says the hardware is sr0 but there are no links to this in /dev
everything points to scd0
I have just tested it again and it works OK and no links are broken.
Can someone explin how it works when the phsical device seems to to be sr0 ?
I was comparing it to a sun x4150 where I have installed rehel5 and automount fails and there is a broken link /dev/dvd -> /dev/sr0

Re: dvd/cd to work on rhel 5
Hardware appears to be there.
Perhaps try a test write with cdrecord ?

Re: dvd/cd to work on rhel 5
mount -o ro /dev/scd0 /media
I saw in another forum that the /dev/scd0 device special file do works even when dmesg report sr0.
