DVD reads DVD's but will not read any CD's in SUSE 11.2 .

I have just upgraded from SUSE 10.1 which I used for a few years with good results to OPEN SUSE 11.2.

Everything is fine but for one very strange problem with the DVD writer when a DVD is inserted it automounts and all the files are there.

When I try the same with a CD it does not mount or do anything the drive light flickers and thats all.

The only program that shows any hint of it being present is K3b which shows that its there by reading the CD title but does not show any of the CD contents.

This happens with all CD’s so is not faulty disks one other thing it will play audio disks normally.

Does anybody know how to fix this please.

I would check your notifier settings in the icon tray. First off, I use KDE and I set the Notifier to be visible all of the time in System Tray Settings. Then, right click the Notifier and select Device Notifier Settings. Look through what it does with CD’s as there may be no auto option to load with a File Manager set. You may be able to press the Notifier icon once with a CD in your optical drive and pick some action for it. I think that CD’s are treated as Audios CD’s by default, which do not get mounted by default unless you set some other action to occur.

Thank You,

What are the CD contents and where were they written? (I mean, by you? Or commercial? and if by you was it in Linux)

How old is the drive? It is possible that CD reading is broken while DVD reading is ok. They are separate lasers.

Thanks for all the suggestions but have tried the notifier and nothing happens but as soon as a dvd is in or an audio CD the notifier comes straight up and confirms what it is.

I have tried commercial CD’s with programmes for windows on CD’s written in Linux and all sorts and none mount.

Its not the drive either as its fairly new and works with windows as does all the CD’s.

As I write this its playing a audio CD of Van Morisson !!!.

Thanks for all the suggestions.

Remember that Audio CD’s do not get mounted like Data CD’s would. They are usable with programs like KSCD and rip-able by asunder or even K3B, but they do not contain a conventional directory on them. I have a thread on how drives are named which has some affect on how they work. It is not a real issue when you have only one drive, but it might be worth a read:

Multimedia Optical Drive Naming (ie /dev/dvd & /dev/cdrom) Howto in openSUSE

Thank You,

I’d be inclined to look in the system message log to see if there are any
messages when you mount the discs.

Do (in a terminal window):

su -
tail -f /var/log/messages

Then insert one of the data CDs and see what messages show up - paste
them up here in code tags (for readability) if there’s nothing obvious to
you indicating why the discs aren’t being read.

Hi Jim

just done what you suggested and sure enough it brings up a whole stream of IO errors so I guess it must be a hardware problem after all so I am about to try another drive but here is some of the message.

Its too long to send it all but it looks fairly obvious now as to what is happening I’ll let you know how the other drive fares funny how it still reads all disks in windows though.

Thanks for all the help
John.

That is bizarre - it could be a kernel issue as well, or I suppose it
could possibly be something as simple as needing to be cleaned (if it’s a
drive that’s seen long service, that’s entirely possible).

It could also be that you’re seeing success in Windows with it if the
Windows driver is being more persistent - it may be seeing errors but
forcing more attempts at recovery, or it may be ignoring the errors
completely (both possibilities are viable IMHO).

Glad though that we could get you pointed in a direction. :slight_smile:

Thanks to everybody on this one,

now my very old dvd burner is back in (its the one I always used with SUSE 10.1 anyway) it reads all sorts including really scratched grotty CD’s I never thought for a second it could be hardware but it must be.

I only changed it because I thought it would be a good idea to have a new one it was badged as a Samsung by the way.

There we go you learn something everyday.

Thanks very much
John.
